Durant exited with what appeared to be an arm injury and was ruled out for the game shortly after, so it was clear that this could be a serious injury.
Durant, 29, is in the final year of his two-year, $2.365 million contract and will make a base salary of $1.25 million for the 2014 season.
Heading into Week 9, Durant has recorded 39 tackles, one interception, two forced fumbles and a recovery over the course of five games. Pro Football Focus has Durant listed as the No. 12 outside linebacker in a 4-3 defense out of 34 qualifying players.
