DENVER -- Tim Tebow is the No. 3 quarterback for the Denver Broncos' game against the Indianapolis Colts on Sunday, with Brady Quinn leapfrogging the rookie for backup duty behind Kyle Orton.

Tebow had been the backup for the first two weeks but played just three snaps, running twice for 2 yards in the opener at Jacksonville, then watching last week's win over Seattle from the sideline.

Also, cornerback Andre Goodman (thigh) is out, replaced by rookie Perrish Cox, and tailback Knowshon Moreno (hamstring) and right tackle Ryan Harris (ankle) are deactivated by the Broncos.

Colts left tackle Charlie Johnson (sprained right foot) has been replaced by undrafted rookie Jeff Linkenbach in the lineup, and rookie linebacker Kavell Conner replaces Clint Session (hamstring). Also, wide receiver Austin Collie replaces Pierre Garcon (hamstring).
