Washington Redskins rookie defensive end Jonathan Allen suffered a lisfranc injury in Sunday's game against the San Francisco 49ers, per Master Tesfatsion of the Washington Post.
Head coach Jay Gruden predicted the injury will keep him out three to four weeks.
The 22-year-old had started all five games this year, tallying 10 tackles and one sack.
Allen emerged as one of the most talented prospects in the 2017 NFL draft after racking up 22.5 sacks across his final two seasons at Alabama. The versatile lineman has the potential to become a stalwart of the Redskins' front seven.
