DENVER — The Broncos announced nine players on Saturday evening who are not expected to play in the team's preseason opener against the Minnesota Vikings.

Wide receiver Corey "Philly" Brown, safety Su'a Cravens, cornerback Tramaine Brock, linebacker Joe Jones, linebacker Todd Davis, offensive lineman Menelik Watson, tight end Jeff Heuerman, tight end Troy Fumagalli and defensive end Clinton McDonald are not expected to participate.

Brown suffered a concussion earlier in training camp and has slowly worked his way back to the field.

Both Cravens and Heuerman have dealt with knee soreness, though Heuerman has participated in field workouts in recent days. They were both ruled out Thursday by Head Coach Vance Joseph.

Watson was also ruled out on Thursday with a pec injury.

McDonald missed the last couple of practice for the Broncos as he was evaluated for the same shoulder injury that plagued him in the spring. He was named a game-time decision along with Joe Jones (sore foot).

Davis took a helmet to the sternum a few days ago, and while Joseph said he was fine, the Broncos appear to be taking every precaution to keep him healthy. The same likely goes for Fumagalli, who was battling a slight groin injury.

The rest of the Broncos are expected to play, with the starters receiving no more than two series of action.

UPDATE: Outside linebacker Von Miller and guard Ron Leary will also not play on Saturday night.
