Vikings defensive tackle Sharrif Floyd, who spent the 2017 season on the team's non-football injury list as he tried to return from a nerve issue in his right knee, still is awaiting the settlement of a grievance he filed in September in hopes of recouping his full $6.757 million salary for the 2017 season. According to sources with knowledge of the situation, Floyd was paid a $2 million base salary for the 2017 season, in addition to a $6,450 workout bonus. Teams are not obligated to pay players on the NFI list; they can pay an amount of their choosing to those players, or opt not to pay them at all. The issue behind Floyd's grievance, however, is whether his knee issues should have been classified as a non-football injury in the first place. Floyd's knee issues stem from arthroscopic surgery he had to repair his meniscus in September 2016. He played only 25 snaps in the Vikings' 2016 season opener in Tennessee, and missed the team's second game against Green Bay before undergoing surgery Sept. 22. The operation disrupted a nerve in Floyd's right knee that has prevented his quadriceps muscle from firing properly, and the issues ultimately caused him to miss the 2017 season. He said in May that his return to the field was "just a matter of when," but was uncertain whether it would happen in 2017. "I feel like progress is being made," Floyd said at the time. "Again, it's just taking its sweet old time." At this point, Floyd's chances of resuming his career appear remote. The Vikings declined to comment on this story. Settlement negotiations in the case are ongoing.
