Tim Tebow is the Back-up. They are moving Gavin Dickey back to WR and he will be the emergency QB. Tebow came in the Spring so if Leak goes down then Tebow will be in. However I don't think Tebow will be ready right now as a passer, But he really is a great runner. Not really fast but can run with the Football. I think he will become alot better passer with Meyer helping him and I can't wait!
