The team sought to curb the circus that's sure to surround Tebow this off-season by declaring him the incumbent at a season-ending news conference Monday.
John Elway, a Hall of Famer who rejoined the team a year ago as chief of football operations, has pledged to work with Tebow this off-season to polish his passing game.
Tebow took over a 1-4 team in October and guided the Broncos to their first playoff berth since 2005. His 80-yard TD toss on the first play of overtime beat Pittsburgh in the wild-card round before the Broncos lost at New England Saturday.
Tebow is the Broncos' only quarterback under contract for 2012.
