Mike Tomlin claims he's indifferent to the minicamp absence of Le'Veon Bell, who hasn't signed his franchise tag and thus isn't under contract.

"I really am," Tomlin said. "It's a waste of my time to focus on the guys that are not available to me, whether injury or otherwise. I tend to focus on the guys who are here and working. I think that's appropriate when you're in my position."

Under the franchise tag, Bell can't participate in offseason work with the Pittsburgh Steelers unless he signs a waiver.

Bell's franchise tag is $12.1 million, but both sides are working toward a long-term extension and have until July 15 to complete one.
