Lions punter Kasey Redfern is done for the year. Redfern suffered a torn ACL, MCL, and partial tear of the patellar tendon in Sunday’s game against the Cardinals, Dave Birkett of the Detroit Free Press tweets. Redfern will be placed on injured reserve, likely later today or tomorrow. 
The injury took place after Redfern bobbled a snap in the Lions’ end zone and ran with the ball. He was hit hard around the ten-yard line – shy of the first down marker – causing his leg to hit the ground at an awkward angle.
Redfern was signed to serve as the team’s punter while Sam Martin is on the non-football injury list. The Lions will now have to look into a Plan C. Kicker Matt Prater took over punting duties on Sunday, but the Lions will almost certainly sign a full-time punter this week.
