A sprained ankle may keep Florida quarterback Jeff Driskel out of the seventh-ranked Gators\' game against Jacksonville State Saturday, his coach said. Coach Will Muschamp said Monday Driskel, who was injured during the Gators\' 27-20 win over Louisiana-Lafayette, was listed as \"probably doubtful\" because he still had \"some swelling\" in the ankle. \"It\'s a little black and blue, I think. It is a sprained ankle,\" Muschamp said. \"We will find what he can do. He is in a walking boot right now. That is precautionary, that is what we always do with sprained ankles. We will see how the swelling goes. Some guys recover quicker than others.\" Driskel has thrown for 1,324 yards and 10 touchdowns with three interceptions this season. If he isn\'t able to practice Wednesday, Jacoby Brissett will start in his place, Muschamp said. \"I\'ve got all the confidence in the world that Jacoby will play well,\" the coach said.
