The Miami Dolphins running back, who was reinstated last month after a one-year suspension for violating the NFL's substance abuse policy, suffered a torn chest muscle in the Dolphins' 3-0 loss to the Pittsburgh Steelers on Monday night, the Palm Beach Post reported, citing an unnamed source.

The injury apparently happened when Steelers linebacker Lawrence Timmons, pursuing a Williams fumble, stepped on Williams' right shoulder blade.

"It's just sad," Williams' agent, Leigh Steinberg, told the Post. "As hard as he's worked. He worked so hard physically to get back into shape and in therapy. He worked so hard for that moment and to have it end this way is sad."

The Post reported the Dolphins were not available for comment Tuesday afternoon.
