Alabama, LSU head to overtime

Posted by ESPN.com's Chris Low

BATON ROUGE, La. -- If Alabama is going to hang onto its national championship hopes, the Crimson Tide will have to do it in overtime.

LSU's Ricky Jean-Francois went skyward to block Leigh Tiffin's 29-yard field goal attempt as time expired in regulation.

The two teams head to overtime tied at 21-21, and a once quiet Tiger Stadium has become unglued.
