Leon suffered a concussion early in Tuesday's loss at Vanderbilt and hasn't been cleared to practice or play. Coach Mike White on Friday called Leon's status a ''probable absence.''
If he doesn't play, the Gators are likely to use a three-guard starting lineup featuring KeVaughn Allen, Chris Chiozza and Kasey Hill.
Center John Egbunu says: ''We definitely got to pick up the slack. You know he's really good and brings a lot of energy to the team.''
