Mike Tomlin: 'Le'Veon Bell could make injury return this week'

Pittsburgh Steelers head coach Mike Tomlin has revealed that running back Le'Veon Bell could return to action this week.

The rookie has been sidelined since the pre-season with a foot injury sustained in his side's warm-up game against the Washington Redskins.

However, he could make his debut at Wembley when the Steelers travel to London to face the Minnesota Vikings.

Tomlin told reporters: "He perked up dramatically at the end of last week. We're excited about watching him be a full participant this week during the course of practice and let that dictate his play.

"He has been doing a nice job of working from a rehabilitation standpoint. We're optimistic about his availability.

"We'll let the practice process be our guide in deciding how much work he gets in the football game."

Pittsburgh are 0-3 in their season after week three following their defeat to the Chicago Bears.
