Coach Mike Tomlin reiterated Saturday that Harmon sprained his knee and is week-to-week. Gerry Dulac of the Pittsburgh Post-Gazette reported that it's a sprain to Harmon's MCL, an injury that will keep him out only 4-6 weeks.

The Pittsburgh Steelers held their breath as an organization in Thursday’s preseason finale against the Carolina Panthers. First-round pick Derrick Harmon suffered a knee injury that required him to be carted to the locker room from the sideline, which led many to fear the worst. However, a serious catastrophe was avoided.

Harmon’s knee injury caused quite a stir on social media, leading Steelers fans to air out their grievances over losing a talented rookie for an extended period of time. But it’s safe to say Tomlin’s latest update may have eased some of those concerns.
