ENGLEWOOD, Colo. (AP) – Denver Broncos coach John Fox has seen enough to name Kyle Orton his starting quarterback.

What he hasn’t determined is who’s No. 2.

Fox said Tim Tebow and Brady Quinn have two more preseason games to win the job as Orton’s primary backup.

Because the league’s new rules don’t mandate teams designate their quarterback rotation on game day any more, the winner of that QB competition might remain a mystery, barring an injury to Orton.

The Broncos began training camp trying to trade Orton but when no teams made an offer, they opened the competition and Orton quickly showed he was the best of the bunch. He’s gotten almost all of the work with the starters.

Tebow continues to struggle with accuracy and mechanics and Quinn has shown vast improvement.
