Jarwin (hip) will not play Sunday against the Broncos, Rob Phillips of the Cowboys' official site reports.
Jarwin had yet to practice this week, so this news doesn't come as a big surprise. He picked up the injury in the Cowboys' Week 8 win over the Vikings. With Jarwin out, the newly activated Sean McKeon (ankle) and Jeremy Sprinkle will look to pick up the extra tight end snaps behind starter Dalton Schultz.
