Bucs quarterback Josh Freeman did not throw in practice Wednesday and is day-to-day with a right shoulder injury, coach Raheem Morris said.

Freeman was injured on a fourth-and-1 quarterback sneak in which he fumbled the snap in the Bucs' 23-17 loss to the Tennessee Titans Sunday.

Morris said Freeman participated in some hand offs but did not attempt any passes in practice Wednedsay. He said Freeman will take mental reps the remainder of the week and could play if he is able to throw well enough by Saturday or even before the game Sunday.

"He hurt his shoulder at the end of the game on that sneak, the bobbled sneak,'' Morris said. "He got tackled and kind of hurt his shoulder. It's sore. Right now, he's day-to-day. We were hoping he'd be able to be full go today. He was limited. We'll have an opportunity to hopefully evaluate him tomorrow and the day after that and get him going to see whether he'll get a chance to play.''

Backup quarterback Josh Johnson took the reps with the first team offense on Wednesday. Morris said Freeman probably could have thrown the football Wednesday, but trainers felt it was best to give him a day off. "He could've thrown it, I didn't ask him to,'' Morris said. "He went out there, handed the ball off, executed our run plays, did all that stuff in the run game and he watched J.J.''

What does Freeman have to do this week to prove he can play Sunday against Carolina?       

"He's got to go out there and execute the gameplan,'' Morris said. "If he can go out there and execute the gameplan and give us the best chance to win, then he'll play...he's just got to go out there and practice.

"Josh is one of those guys who will go all the way up until Saturday...potentially, even Sunday. He's one of those guys who's going to get all the mental reps, the mental capacity, all that type of thing. And if he can throw it, then he can throw it. And if he can't, then he can't.''

What makes matters worse, according to Morris, is that Freeman was hurt just trying to execute the quarterback/center exchange.

"That's the  shame of it,'' Morris said. "Executing the most simple play of football, the quarterback-center exchange. We didn't execute it and got our quarterback hurt, potentially.''
