Redskins rookie Jonathan Allen has a Lisfranc sprain will be out for three or four weeks, Ian Rapoport of NFL.com (on Twitter) hears. Allen, a first-round pick, has been starting on the defensive line, moving between end and nose tackle. 
Allen, an Alabama product, was regarded by many as a top five talent in this year’s class. However, on draft night, he slipped all the way to Washington at No. 17 thanks to his medical history. The foot injury, however, appears to be a new one. In college, Allen was plagued by arthritic shoulder pain.
Through five games this year, Allen has ten tackles and one sack. Pro Football Focus has him categorized as an interior defender and he ranked No. 32 in that group of 122 qualified players.
As a senior in 2016, Allen had 69 tackles, including 16 tackles for a loss. He also had 10.5 sacks, nearly matching his 12 sack total from 2015.
