Kubiak holds off on naming starting QB for preseason opener (Yahoo Sports)

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.
