Pittsburgh fans can breathe a sigh of relief—rookie Derrick Harmon’s knee injury isn’t as bad as first feared. After a scary moment in the preseason finale, the team now says Harmon only has a mild sprain and won’t be heading to injured reserve. There’s even a chance he’ll miss just the season opener, which is a huge boost for the defensive line. This means more reps for Keeanu Benton and a chance for Yahya Black to step up. How do you think the defense will hold up if Harmon sits out Week 1? #Sports #Football #Steelers
