In Friday's play, Sindelar teed off but felt pain in his lower back on his second shot of the first hole. He played through the fourth hole before seeking treatment and Cook played solo the rest of the way, posting 6 under on his own ball and completing a 7 under day for the team, leaving them tied for 16th and three shots off the lead.
"I had the perfect partner this week but unfortunately, I can't play. This is the only time of the year where we can play with a good friend in a team competition and the people here in Savannah are wonderful," Sindelar said Saturday. "I think I'll be fine with some rest and I plan to be ready to go in Birmingham (at the Regions Tradition) in two weeks."
Under tournament rules, Cook could have continued to play alone in the team format, with his former Ohio State University teammate playing some holes or none at all. Sindelar hinted Friday that he may have been able to return Sunday, but when that was no longer an option, Cook declined to continue.
"This is a team event and I didn't want to just play all 54 holes without Joey as my partner. If he would have told me that he could probably go on Sunday, I would have stayed in the competition, knowing I'd have him back for the final round," Cook said. "The fun of the Liberty Mutual Legends of Golf is the team concept."
The pair had finished progressively better in the previous three years at the Westin Savannah Harbor Golf Resort -- fourth, third and then second last year after losing to Nick Price and Mark O'Meara in a playoff.
Cook came into the week as the hottest player on the Champions Tour, having picked up his second win of the season last week at the Outback Steakhouse Pro-Am. He defeated Jay Don Blake in a playoff, and ironically Blake was near the first tee in Savannah Friday morning as the first alternate and would have played with Cook had Sindelar withdrew prior to the start of play.
