Brock Osweiler has a lot to celebrate today - not only is he playing his first NFL game as a starting quarterback, but it's also his 25th birthday!

Osweiler and the Denver Broncos take on Jay Cutler and the Chicago Bears at Soldier Field while Peyton Manning, 39, is at home recovering from a partially torn fascia and other injuries.

Osweiler has played in the NFL for 4 years.

Happy birthday, Brock Osweiler!
