Freiermuth (shoulder) caught his only target for six yards in Thursday's 24-16 preseason win over Philadelphia.
Freiermuth made his Steelers debut after sitting out the Hall of Fame Game against the Cowboys. The rookie second-round pick was called for a holding penalty on Pittsburgh's opening drive but managed to catch a pass in the second quarter. With established veteran Eric Ebron topping the tight end depth chart in Pittsburgh, Freiermuth will likely be brought along slowly, though he'll try to outplay Ebron when the Lions come to town for more preseason action next week.
