There’s more information now on Steelers first-round pick Derrick Harmon, who was carted off the field in last night’s preseason matchup.

According to NFL Media’s Ian Rapoport, Harmon suffered an MCL sprain that will keep him sidelined for about a month.

That makes him a candidate to begin the season on injured reserve, though he’ll be able to return.
