Tebow back at practice

Posted by ESPN.com's Chris Low

Florida quarterback Tim Tebow was back at practice Tuesday, but still has to be cleared for contact and to play in the game.

It's the first football-related activity he's participated in since suffering a concussion on Sept. 26 against Kentucky. Wearing a non-contact jersey, Tebow was working with the starters and throwing passes to the first-team receivers.

A person familiar with the situation told ESPN's Joe Schad that doctors were satisfied with the progress Tebow has shown in balance, equilibrium and memory testing. He must reach certain measurable standards to progress to the next level in his participation.
