Redskins cornerback Chris Culliver suffered tears of both his ACL and MCL in practice on Thursday, a source told CSN Mid-Atlantic.
Ian Rapoport of NFL Media was the first to report the news via Twitter.
Culliver, the starting right cornerback, left the facility sporting a heavy duty brace and walking with the aid of crutches.
“He jumped up for the ball [and] landed on it,” Coach Jay Gruden said. “We’re getting him checked out now.”
Culliver, who signed a four-year, $32 million free agent contract with the Redskins this offseason, has endured a difficult first season in Washington.
He was suspended one game for violating the NFL's personal conduct policy during his tenure with the 49ers. The 27-year-old has also missed three games due to swelling and discomfort in his left knee. He missed the entire 2013 season in San Francisco after tearing the ACL in that knee.
On top of all that, he’s also dealing with a shoulder injury that he suffered against the Panthers. An MRI on his shoulder is set to be shared with a doctor for a second opinion, Gruden said Thursday.
With Culliver is sidelined, he would likely be replaced by veteran Will Blackmon, who filled in for him earlier in the season.
