Jeremy Maclin was taken to the locker room on a cart after his knee got tied up following a reception in the third quarter.
Chiefs coach Andy Reid said after the game that Maclin strained his knee and will have an MRI on Sunday, but NFL Media Insider later reported Maclin's injury indeed is to his ACL. Rapoport adds it's not definitive that Maclin tore his ACL and Sunday's tests will determine the severity of the injury.
Maclin exited the game with three catches for 29 yards on four targets. The Chiefs took a 20-0 lead on the drive Maclin got injured.
Maclin previously tore ACL in his right knee in 2013 (with Eagles) and 2009 (in college at Missouri).
