One day after using his backup quarterback as an emergency wide receiver, Fox reiterated: "He is a quarterback."
But in a pinch, Tebow makes an interesting decoy. Not that Fox wants to travel down that road again.
And when Eddie Royal (groin) was hurt early in Sunday's contest, the Broncos were down to just two receivers: Eric Decker, who was making his first career start, and Matt Willis, who has only one start in four NFL seasons.
That forced Fox to use Tebow for a handful of plays out wide, especially since the former University of Florida standout knew the offense so intricately.
Tebow donned his receiver's gloves and ran the routes just like he was supposed to, even if Kyle Orton hardly glanced in his direction.
On Monday, Fox joked that Tebow stepped in and "actually graded 100 percent."
No joke: Tebow won't be switching positions anytime soon.
"We'll list him on the program as a quarterback," said Fox, who earned his first win with Denver as the Broncos fended off the Bengals 24-22. "Tim wants to win, like everyone in that locker room. He does have a skill set outside of a lot of quarterbacks."
The Broncos might be shorthanded at wide receiver for a while. The Denver Post reported Monday that Royal will miss at least two weeks and might not return to play until after the team's bye in Week 6.
