Awaiting timeline, Diontae Johnson admits injury 'frustrating'

PITTSBURGH -- Steelers wide receiver Diontae Johnson says he is remaining positive and level-headed amid an unclear timeline for his return from a hamstring injury.

"It sucks," Johnson said Thursday, adding that no decision has been made about placing him on injured reserve. "It's the first game, didn't get to really do what I wanted to do out there, but it's frustrating.

"But at the same time, my teammates keep me up, my little son keeps me up. I can't just be in a bad mood; that's not going to do nothing about the situation. All I can do is just keep being a leader from our group, just coming in with a positive energy or a smile on my face and just keep attacking this rehab."
