Last week, the Broncos surprisingly demoted rookie quarterback Tim Tebow from No. 2 to No. 3, even though Tebow was under the impression that he’d be the primary backup all year.
In the aftermath, Broncos coach Josh McDaniels suggested that the identity of the backup will be determined on a week-by-week basis.
For this week, against the Titans, the decision has been made to move Tebow back to No. 2.
The difference is significant. As the primary backup, Tebow can enter the game at any time, either if starter Kyle Orton is injured or if the Broncos want to use Tebow in their single-wing offense.
At No. 3, if Tebow enters the game at any point before the fourth quarter, neither of the other two quarterbacks (Orton and Brady Quinn) can return.
