Adrian Peterson said he suffered a dislocated shoulder during Monday night's game between the Washington Redskins and New Orleans Saints.
Jay Gruden initially called the injury a strained shoulder and said Peterson would get an MRI on Tuesday to determine if there's any issue.
"It's not going to keep me out," Peterson said. "I came back into the game. It was just a situation where it was sore.
"I just thank God it wasn't worse."
Peterson finished Monday's game with four carries for 6 yards and two catches for 36 more.
