Surprise! Peyton Manning is a Broncos captain.

OK, that's no a surprise. Actually, there were no surprises when the Broncos elected their five captains for the 2014 season — two from the offense, two from the defense, one from special teams.

In a vote by the players, Manning was joined by wide receiver Demaryius Thomas, defensive end DeMarcus Ware, defensive tackle Terrance Knighton and special teams ace/safety David Bruton.

"When you’ve got that 'C' on your jersey, you’re almost obligated to do things right,” Knighton said Monday.

Denver hosts the Indianapolis Colts in their season opener on Sunday. The Broncos held their first practice of game week at Dove Valley on Monday. Wide receiver Wes Welker participated in practice, though he hasn't been cleared to play Sunday.

"He's still in the (NFL) protocol. He's still exercising. (We) feel good about his progress," coach John Fox said. "We will keep you posted (on) Wednesday but obviously as I said all last week, he is a guy that we'll be cautious about. Our main concern is his safety."

Welker was named a team captain last season after Ryan Clady went down with an injury.
