Jake Plummer and Clinton Portis both were sidelined in Denver’s 37-13 romp at San Diego Sunday.

Plummer separated his right shoulder diving for a first down, but stayed in for two more plays, long enough to throw his third touchdown. Denver coach Mike Shanahan had the team announce Plummer’s injury was a concussion. He admitted afterward he lied.

“If Steve (Beuerlein) went down on the first or second play, and Jake went in there with a separated shoulder, they would know that we could not throw the football,” Shanahan said. “So, for his sake and our sake, I had to fib a little bit.”

The Broncos dominated the Chargers despite losing Plummer and Portis, who suffered a chest bruise and missed the second half. Portis had 129 yards on 12 carries.

Arizona lost quarterback Jeff Blake with a bruised left heel in the first quarter of its 38-0 loss to Seattle. X-rays were negative, but backup Josh McCown played the rest of the game.

The Jaguars also lost receiver Jermaine Lewis (knee) and cornerback Kiwaukee Thomas (groin) for the game. Del Rio said Lewis’ injury could be serious.
