Detroit Lions linebacker Derrick Barnes sustained a knee injury during the game against the San Francisco 49ers (#DETvsSF). He was seen down on the field and subsequently limped off with assistance from trainers. Barnes' return to the game is questionable as he was observed testing his knee on the sidelines, performing lateral movement drills.
