The Broncos failed to score on their first dozen possessions, and with the Bears leading, 10-0, with 2:08 left in the game, it looked as if Tebow Time would expire. But Tebow went 7-for-7 on a TD drive to get Denver within a field goal, and then led a drive that forced OT with a 59-yard field goal by Matt Prater, who nailed a 51-yarder in the extra period to end it.
