ENGLEWOOD, COLO. • Tim Tebow missed some practices but none that counted before agreeing to a contract with the Denver Broncos on Thursday.

The two-time national champion from Florida and 25th pick in the NFL draft missed the first three workouts for rookies and selected veterans while his agent, Jimmy Sexton, and general manager Brian Xanders hammered out a deal worth $11.25 million over five years, with $8.7 million of that guaranteed.

ESPN reported that Tebow could earn as much as $33 million over the course of the contract.

Tebow was in meetings Thursday night and didn't return messages.

Tebow is expected to practice this morning, the final session before training camp begins in earnest Sunday with a full squad in full pads.

The signing of Tebow leaves top pick Demaryius Thomas, a wide receiver out of Georgia Tech, as the only unsigned member of Denver's draft class.

Thomas was selected three spots before Tebow, the most intriguing pro prospect since Michael Vick.

The Broncos announced Tebow's signing after workouts Thursday. Coach Josh McDaniels wasn't available to comment.

The Broncos' starting quarterback remains Kyle Orton, who threw for 3,800 yards last season but faltered down the stretch when he got banged up and the Broncos kept their offense conservative.

The Broncos were unwilling to commit to a long-term relationship this offseason, so Orton signed a $2.6 million tender as a restricted free agent and didn't miss any of the team's offseason program.

Tebow might not be ready to make a big impact as a rookie because he faces a big adjustment as he morphs from combination college quarterback to prototypical pro passer. Still, many consider him the best college player ever, and he's creating the kind of buzz in the Rockies that John Elway did back in 1983.

Tebow's teammates aren't concerned that he'll crater under all the attention.

"As successful as he's been, I'm sure he can handle it," said 10-year veteran Russ Hochstein.
