Siemian completed seven of 12 passes for 88 yards in Thursday's preseason opener against the Bears.
Siemian played the second quarter, with his four drives leading to two field goals, a blocked field goal and a punt. Granted, the scoring opportunities were largely provided by Denver's defense and special teams, as none of Siemian's drives spanned more than 31 yards. Mark Sanchez, who played the first quarter, turned in a more up-and-down performance, completing 10 of 13 passes for 99 yards, with a touchdown and an interception. The two essentially played to a draw, which would seem to work in favor of the more-experienced Sanchez.
