BATON ROUGE, La. (AP) - LSU quarterback Matt Mauck's right foot is in a cast, and it is unclear whether he will play this week against South Carolina.

Mauck was injured about midway through the fourth quarter of the Tigers' 36-7 victory over Florida on Saturday when he was tackled from behind. He stayed in the game, but coach Nick Saban said Monday the injury got progressively worse.

"The guy tackled him and then rolled over on his foot," Saban said.

X-rays showed no break, though more will be taken because of swelling in the foot. Further evaluation will be done Tuesday night or Wednesday morning, Saban said.

If Mauck can't practice by Thursday, he probably will not play Saturday against South Carolina, and backup quarterback Marcus Randall would direct the Tigers' offense.

Randall and Mauck were expected to be in a tight competition for the starting job until Randall injured his knee in the spring. The two are roommates, and Randall said Mauck has given him advice on what to do if he plays Saturday.

"Me and Matt basically have almost the same style of play," Randall said. "So the gameplan's not really going to change that much. We're still going to run the ball, do our quarterback draws, bootlegs and play-action passes. The offense is going to still stay the same."

Teammates are confident in Randall.

"Marcus is a great leader," offensive lineman Rodney Reed said. "And they bring the same type of attributes as far as strong arm and fairly mobile quarterback. So I don't think we'll have to change our scheme too much."
