Late slip for us on this, but Washington linebacker Reuben Foster suffered a knee injury in practice on Monday that is believed to be a torn ACL.
Foster, a first-round draft pick in San Francisco in 2017, was released by the 49ers last November following multiple arrests and suspensions. Washington signed him, then he was placed on the commissioner's exempt list by the NFL; the league has since determined that Foster would be fined two game checks, but not suspended.
It is possible Foster could recover from a torn ACL and play late this season. Chargers tight end Hunter Henry tore his ACL one year before Foster tore his, almost to the day, and returned to start in L.A.'s playoff game against New England.
