Organized team activities began Monday for NFL teams, and Washington suffered a loss shortly after the opening of camp.
Former 49ers linebacker Reuben Foster went down during the second play of OTAs with what appeared to be a serious left leg injury. He was on the ground for several minutes before being carted off while in tears.
After an receiving an MRI, Foster's injury appears to be very serious.
That's a brutal development for Foster and Washington.
Foster was drafted by the 49ers with the No. 31 overall pick in the 2017 NFL Draft, which was the beginning of a tumultuous time in the Bay Area.
The Alabama product was arrested three times and suffered multiple on-field injuries during his time with the 49ers. San Francisco cut ties with Foster last November after he was accused of committing domestic battery at a team hotel in Florida.
Washington claimed the linebacker off waivers a few days later. Foster recorded 84 solo tackles in his 16-game career with the 49ers.
The 49ers have since revamped their linebacking corps after Foster's departure. They signed Kwon Alexander to a four-year contract in the offseason and spent a fifth-round draft pick on Arkansas' Dre Greenlaw.
Kyle Shanahan and John Lynch hope Alexander, once he gets fully healthy, and Greenlaw can fill the role left by Foster's departure in the middle of the defense.
