Redskins defensive lineman Jonathan Allen could miss three to four weeks with a Lisfranc sprain, Jay Gruden announced Monday.

The rookie out of Alabama has been a key contributor, with 10 tackles and one sack through his first five starts. The Redskins face the Eagles, Cowboys, Seahawks and Vikings over the next month. He suffered the injury in the fourth quarter of Sunday’s 26-24 victory over San Francisco.

Kicker Dustin Hopkins suffered a “right hip rotator muscle strain” and is listed as “week-to-week.” Hopkins made both field goal attempts Sunday, but missed an extra point following a pivotal fourth-quarter touchdown. The Redskins will work out kickers this week with his health up in the air.

Cornerback Bashaud Breeland (knee sprain) could be limited in practice this week, however Gruden believes there’s a chance he could go against Philadelphia. The Redskins were already beaten up in the secondary, relying heavily on young defensive backs Fabian Moreau and Joshua Holsey, as well as veteran DB Quinton Dunbar, to fill the void left by Josh Norman.

Norman suffered a fractured rib in Washington’s loss two weeks ago to Kansas City. He was expected to miss four weeks.
