PITTSBURGH (AP) — Pittsburgh Steelers wide receiver George Pickens says he needs to not let frustration get the best of him. Pickens has been limited in recent weeks while opponents search for ways to stop him. That frustration may have bubbled over in a victory over Tennessee when Pickens didn’t appear to be in the mood to celebrate after teammate Diontae Johnson caught the game-winning touchdown. Pickens briefly deleted all of the Steelers-related content from his Instagram page shortly after the game, though Pickens says the “scrubbing” of the page had nothing to do with football. Some of the Steelers content has been restored.
