Jags' Maurice Jones-Drew doubtful

The Jacksonville Jaguars' playoff hopes took a setback last week when the Jaguars lost to the Indianapolis Colts, but the situation might be tougher Sunday if halfback Maurice Jones-Drew doesn't play.

Jones-Drew didn't practice Friday because of a knee injury and is doubtful for Sunday's game against the Washington Redskins. It's the third straight day that Jones-Drew has missed practice.

Coach Jack Del Rio declined to reveal whether he expects his star to try to play against the Redskins. Del Rio said the Jaguars are "going to monitor his condition throughout the weekend."

Jones-Drew has dealt with knee problems most of the season, but his right one really became problematic after his sixth consecutive 100-yard game, Dec. 12 against Oakland. He missed two days of practice last week, and Indianapolis held him to 46 yards on the ground.

He sat out practice Wednesday, Thursday and Friday this week.

Normally, a Jaguars player who doesn't practice on Friday doesn't play on Sunday.

Linebacker Justin Durant remains out with a groin injury. Guard Justin Smiley is doubtful with a concussion. Wide receiver Mike Sims-Walker is questionable with an ankle injury.
