Maurice Jones-Drew's status in doubt

JACKSONVILLE, Fla. -- Jaguars running back Maurice Jones-Drew will not practice until Friday at the earliest and his status for Sunday's game against the Buffalo Bills is in doubt because of a hamstring strain.

"We'll just keep monitoring his progress and see how he does," coach Gus Bradley said Monday. "That might be towards the end of the week that we have a better idea where he's at."

Jones-Drew, who suffered the injury in the fourth quarter of last Thursday's victory over the Houston Texans, said he is feeling better and is optimistic that he'll be available Sunday.

"You never know," said Jones-Drew, who had an MRI exam Friday. "We could have a miraculous turnaround tonight. You never know, but we'll see how it goes."

If Jones-Drew is unable to play, first-year player Jordan Todman would start and his backup would be rookie Denard Robinson, who was drafted as a receiver but was moved to running back in October. Todman, the team's primary kick returner, has run for 138 yards and two touchdowns. Robinson has 27 yards on 17 carries.

Jones-Drew has rushed for 719 yards, with 264 coming in the past three games. He had a season-high 103 yards against the Texans -- his first 100-yard game since Week 3 last season -- and set up the Jaguars' final touchdown with a season-long 48-yard run in which he broke four tackles.

Jones-Drew was injured as he was tackled by linebacker Brooks Reed after a 15-yard catch-and-run with 11 minutes remaining.
