ENGLEWOOD, Colo. (AP) -- Denver quarterbacks Mark Sanchez and Trevor Siemian will play the first half of the preseason opener at Chicago on Thursday night.
Coach Gary Kubiak held off on choosing a starter, though.
Sanchez and Siemian are listed as co-No. 1s on the depth chart as neither has shown himself as the clear-cut starter for the Super Bowl champions.
Kubiak said he would later Tuesday with his staff to decide who would take the first offensive snap Thursday. He said the game plan is to play Sanchez and Siemian a quarter each, and to have rookie Paxton Lynch play the second half against the Bears.
The Broncos traded for the veteran Sanchez after Peyton Manning retired and Brock Osweiler signed with Houston. Siemian, Denver's third quarterback for most of 2015, impressed in offseason workouts to make training camp a quarterback competition.
