Pittsburgh Steelers defensive lineman Derrick Harmon suffered a sprained MCL that could keep him out one month, according to NFL Network’s Ian Rapoport. Harmon could begin the season on injured reserve with a designation to return, which would keep him out at least the first four months of the season.
#Steelers first-round DT Derrick Harmon, who was ruled out with a knee injury last night, was diagnosed with an MCL sprain, sources say. He’s expected to be out about a month, which makes him a candidate to begin the year on IR.
