Buffalo Bills rookie wide receiver Sammy Watkins bruised his ribs and didn't return after playing against the Pittsburgh Steelers.
"They're going to run tests and everything and we'll see how he is," coach Doug Marrone said.
Watkins got injured on a hit from Steelers rookie linebacker Ryan Shazier.
Watkins isn't expected to miss much time.
"I think Sammy will be fine," Bills quarterback EJ Manuel said. "Hopefully he'll come back and bounce back from whatever little injury he had."
