LANDOVER, Md. (AP) -Washington Redskins running back Clinton Portis' streak of 40 consecutive starts came to an end when he was inactive against the Denver Broncos because of a concussion.

Portis held the longest active streak among NFL running backs. He was injured in last week's game at Atlanta.

Ladell Betts, who had been questionable with a sprained ankle, was active for Sunday's game and was expected to start in Portis' spot.

Also among the inactives for the Redskins were tight end Chris Cooley and offensive lineman Mike Williams. Both have ankle injuries.

Denver's inactive list included defensive lineman Ryan McBean (knee), safety Josh Barrett (hamstring) and right tackle Ryan Harris (toe).
