Coach Mike Tomlin revealed Friday that Freiermuth is dealing with a hamstring injury, Brooke Pryor of ESPN.com reports.
Freiermuth was forced out of Thursday's practice early, with what was described as "some lower-body tightness." Now we know that the tight end -- who didn't practice Friday -- is managing a hamstring concern. Next up for practice reps in Freiermuth's absence are Zach Gentry, Kevin Rader and Connor Heyward.
