ORLANDO, Fla. -- Peter Hanson withdrew from the Arnold Palmer Invitational presented by MasterCard on Thursday morning, citing a neck injury.

Because Hanson had yet to tee off -- he was in the afternoon wave -- he'll be replaced by Chris Stroud.

Hanson had played well in his last two starts, tying for eighth at the World Golf Championships-Cadillac Championship and 13th at The Honda Classic.
