Got it, from MLB TB site:
BOSTON -- Carl Crawford landed funny on his right shoulder on Tuesday night when he dived trying to catch Manny Ramirez's third-inning double. Wednesday, he was scratched from the lineup with a sore shoulder.
"I don't know what happened," Crawford said. "I stretched out and kind of overextended it or something, to the point where I can't swing the bat now."
Crawford stayed in Tuesday's game and singled in his final at-bat in the ninth.
"I actually played through it last night," Crawford said. "It was hurting. As soon as I dived, I was struggling all night. Came in today to see how I was doing. Knew I was going to be stiff this morning, but I wanted to get it loose and see what I can do."
Crawford doesn't think it's a major injury.
"No popping, nothing like that," Crawford said. "Just hyperextended it a little bit.
"It's day to day. I hope there's nothing that wrong, I'd be disappointed if it was. Just going to treat it real quick and fast, hopefully I'll be in there the next couple of days."
After Crawford was scratched, manager Joe Maddon moved Ty Wigginton from right field to left field, inserted Damon Hollins into the lineup in right, and moved Joey Gathright from the ninth spot to leadoff.
