Back to football as defending champion Broncos open preseason in Chicago

CHICAGO -- Six months and four days since winning Super Bowl 50, the Broncos return to the field for the first Thursday when they open the preseason against the Chicago Bears at Soldier Field.

The big focus will be at quarterback. In the Broncos' first depth chart of training camp released Monday, Mark Sanchez and Trevor Siemian were listed as co-No. 1 quarterbacks.

On Tuesday, coach Gary Kubiak said Sanchez will get first-team reps in the first quarter and Siemian will get second-team repts in the second quarter. First-round draft pick Paxton Lynch will play the second half.

The Broncos were left without a starting quarterback when Peyton Manning retired after winning Super Bowl 50 and Brock Osweiler agreed to a four-year, $72 million contract with $37 million guaranteed with the Houston Texans.

Another area to look at is the revamped offensive line, where Darrion Weems is at guard and Michael Schofield is at left tackle.

And linebacker and Super Bowl 50 Von Miller should see his first action since signing a six-year contract worth $114.5 million with $70 million in guarantees in the offseason.

Because it's the first preseason game, Kubiak said the game is more of a focus for those on the second and third teams.

The Broncos' first home preseason game is Aug. 20 against the San Francisco 49ers.
