FORT WORTH, Texas -- Play was suspended midway through Friday's second round of the Crowne Plaza Invitational at Colonial due to dangerous weather conditions.

Lightning and thunderstorms caused tournament officials to bring in the players from the course at 1:18 p.m. ET (12:18 p.m. ET).

Graham DeLaet is the current leader at 9 under. The Canadian shot a 3-under 67 on Friday morning.

Josh Teater and Jordan Spieth are in the clubhouse at 8 under. Past Colonial champ Steve Flesch is also at 8 under through 15 holes. Flesch is 6 under on his round.

Ryan Palmer, the first-round leader at 8 under, has yet to begin his second round. He was scheduled to tee off at 2:28 p.m. ET.

UPDATE (2:03 p.m. ET): The second round will resume at 2:45 p.m. ET. Players will need to be in position at that time.

FORT WORTH, Texas -- D.H. Lee became the second golfer to withdraw from the Crowne Plaza Invitational at Colonial on Friday with a back injury.

Lee , who shot 76 in the first round, had played 14 holes in the second round after starting his round on the 10th hole. Lee was 6 over on his round and had just triple bogeyed the par-4 fifth when he withdrew. Lee was 12 over for the tournament at the time.

Earlier in the day, Patrick Cantlay withdrew during his round with a back injury.

FORT WORTH, Texas -- Seeing Zach Johnson and Jason Dufner paired together at a PGA TOUR event has become a familiar scene. Especially at Colonial.

A year ago at the Crowne Plaza Invitational at Colonial, Johnson and Dufner were paired in the final two rounds of what essentially turned into match play for the title, as the two separated themselves from the rest of the field. Johnson eventually claimed his second title at Colonial, with Dufner finishing second.

This week, they are playing the first two rounds together, along with last week's winner of the HP Byron Nelson Championship, Sang-Moon Bae. The threesome tees off Friday at 1:33 p.m. ET.

"I totally enjoy it," Johnson, who opened his title defense with a 1-under 69, said about playing with Dufner. "We've always gotten along very, very well. We kind of went through the ranks together from the Web.com to the TOUR."

Said Dufner, who started with a 3-under 67: "It's always good playing with Zach."

Last year's Colonial weekend served as the first of many pairings for Johnson and Dufner the rest of the year. Because of their proximity to each other in FedExCup points during the Playoffs last year, they were paired in the first two rounds at the Deutsche Bank Championship, the first two rounds of the BMW Championship and the first round of the TOUR Championship by Coca-Cola.

Then, of course, they were teammates on the U.S. squad at the Ryder Cup. They won both of their foursomes matches and lost one four-ball match.

Thursday was the first time they had been paired together this year.

"We're pretty familiar with each other's games," Dufner said. "We kind of play a similar game, so it's kind of easy to club off and kind of see how the course is playing."

Said Johnson: "I'd say his ballstriking is a little more consistent than mine overall, but for the most part, we're both pretty consistent."

Having played against and alongside Dufner for the past year, Johnson has come to appreciate his stoic nature.

"He plays very a-motional golf, I would say," Johnson said. "I like that. I like watching it. I like being around that.

"Plus, he's a good friend."

FORT WORTH, Texas -- Josh Teater and Boo Weekley had the hottest starts in Friday morning's second round of the Crowne Plaza Invitational at Colonial but have encountered problems on their final nine holes.

Teater, starting his round off the 10th tee, birdied six of his first 10 holes and had moved to 11 under for the tournament. But he bogeyed the third, sixth and eighth holes after making the turn and is now 8 under with one hole remaining.

Playing partner Weekley birdied seven of his first 11 holes and was 10 under at that point. But he double bogeyed the par-4 fifth and bogeyed the seventh and eighth to fall to 7 under.

Jordan Spieth, the 19-year-old from Dallas, is 3 under on his round and 8 under.

Jim Furyk is 4 under on his round and 5 under for the tournament through 13 holes.

Rickie Fowler, Charl Schwartzel and Angel Cabrera are on the course and are 2 under for the tournaments.

The cut line is currently projected at 1 under.

FORT WORTH, Texas -- Patrick Cantlay was forced to withdraw with a back injury during Friday's second round of the Crowne Plaza Invitational at Colonial.

Cantlay had just bogeyed the par-4 seventh, his third bogey of the day, before deciding to withdraw. He shot a 5-over 75 in Thursday's opening round and was 8 over for the tournament when he withdrew.

Cantlay, playing on a sponsor's exemption, was making just his sixth start on the PGA TOUR this year, and his first in two months. He's a regular member of the Web.com Tour and is currently sixth on the money list.

FORT WORTH, Texas -- Here are a few notable players to watch Friday afternoon in the second round of the Crowne Plaza Invitational at Colonial. TV coverage begins at 3 p.m. ET on the Golf Channel

Zach Johnson (1:33 p.m. ET): The defending champ started off with a 1-under 69, the 16 time in his last 17 rounds at Colonial he's shot in the 60s.

Jason Dufner (1:33 p.m. ET): Last year's runner-up opened with 67 on Thursday. A year ago, he shot 64 in the second round.

FORT WORTH -- Ryan Palmer and John Rollins live about a mile apart from each other in nearby Colleyville, a suburb near DFW Airport. They are members at Colonial Country Club and have played several rounds together.

And now they're dominating the top of the leaderboard after Thursday's first round of the Crowne Plaza Invitational at Colonial.

Palmer shot an 8-under 62 in the morning, and Rollins followed with a 63 in the afternoon, claiming the top two spots after 18 holes. Four players -- Morgan Hoffman; Canadians David Hearn and Graham DeLaet; and John Peterson, the latter having grown up on this course when his family had a membership -- were another shot back at 64.

No dues-paying member of Colonial has won the Crowne Plaza Invitational since the last of Ben Hogan's five wins in 1959. Palmer or Rollins could follow in Hogan's footsteps this week.

"I think it's pretty cool," Rollins said. "It would be fun if we could fast forward this to Sunday."

Palmer actually plays more golf at Colonial than does Rollins does.

"I think he is a pretty permanent fixture in the men's group," Rollins said. "... I know a lot of people know that Ryan is a member. A lot of people may not know that I'm a member here. Hopefully by the end of the week they will."

Neither has enjoyed much success in their previous starts here.

Palmer's best finish in nine starts was his tie for fifth a year ago -- he's only top-10 finish. Rollins has missed the cut in seven of his 10 starts, his best finish a tie for 24th in 2007.

But Palmer's 62 ties for the lowest opening-round score in tournament history. Rollins' 63 was his best round at Colonial by four strokes.

Palmer visualizes his name on the Wall of Champions on the first tee.

"This is what I dream about when I play here every year," Palmer said. "This is the one tournament I gear up for the most."

Rollins is now visualizing a duel with Palmer on the back nine Sunday.

"I hope I come out on top," Rollins said.

Of course, there's a long ways to go, and the leaderboard behind Palmer and Rollins is crowded.

Besides the four players at 64, six more players are at 65, including 19-year-old Dallas native Jordan Spieth. In all, 38 players are within five shots of Palmer's lead.

Hoffmann comes off a tie for fifth at last week's HP Byron Nelson Championship, the best finish of his rookie year. He shot a pair of 66s on the weekend and the momentum obviously carried over to Thursday's first round.

"Last week was a big confidence booster," Hoffmann said.

Defending champion Zach Johnson shot a 1-under 69, as did last week's winner, Sang-Moon Bae, who double bogeyed his final hole.

"It's a fairly solid day," Johnson said. "A day I didn't shoot myself out of it."

FORT WORTH, Texas -- Strong Texas winds usually provide Colonial with its main defense against PGA TOUR pros each year. In Thursday's first round of the Crowne Plaza Invitational at Colonial, the winds barely made their presence felt.

What followed was a bevy of red numbers.

Ryan Palmer tied for the lowest opening round in tournament history with an 8-under 62 to lead the assault on Colonial. Eighty-eight of the 135-man field managed par or better. Scoring conditions were ideal.

"This probably the most docile I have seen Colonial," said Daniel Summerhays, making his third start in this event and starting strong with a 65. "Usually the wind is really going."

"I think we got pretty lucky," said Canadian Graham DeLaet after his 6-under 64 in the afternoon. "The wind really didn't kick up too hard and you kind of expect low scoring out here if you can just keep the ball in play and make a few putts."

Added Matt Every after his 65 in the morning: "There was enough wind to know it was there, but not, you know, nothing crazy."

Even in the afternoon, the winds didn't pick up as expected. Plus, the sun rarely appeared, preventing the greens from firming up.

"We actually caught a good break in the afternoon with the cloud cover and the wind staying down," said 19-year-old Texan Jordan Spieth after his 65.

But don't expect those breaks to remain in effect for all four rounds.

"Today is the day to get it," Tommy Gainey said after a 65. "I feel like the wind is going to pick up the next few days. When you play this golf course and when the wind picks up, you're happy with par."
