PITTSBURGH -- The Pittsburgh Steelers are enjoying their mental reps at organized team activities, which ended this week, but generally they aren't taking this time too seriously. No pads, no problem.

That's why running back DeAngelo Williams isn't concerned with running mate Le'Veon Bell, who participated in individual drills on the first OTA session. Otherwise, things have been quiet as Bell rehabs his torn medial collateral ligament. Teammate Sammie Coates said last week Bell was in treatment.

Williams says Bell is doing well and training.

"Soon as it's time to play real football, he'll be there," Williams said.

Bell has been posting social media videos of him training on a field that does not look like the Steelers facility. He could be with the team for next week's minicamp, but the Steelers might decide to hold him out altogether if he's not medically cleared.

Offensive coordinator Todd Haley said he had a good talk with Bell a few days ago and knows Bell is "working his butt off" to get back. Bell told reporters two weeks ago he's eyeing a Week 1 return.

"He's as competitive a guy as we have," Haley said.

Expect the Steelers to be cautious with Bell at all turns. There's no need to let him loose until live game action -- yes, real football -- gets close.
