Stoke City defender Nathan Collins has had the red card he was given in the 2-2 draw with Barnsley rescinded.

The club successfully appealed against the decision to the Football Association on Wednesday and Collins' three-match ban has been overturned.
"Having watched it back the assistant should never have been making that decision," Potters manager Michael O'Neill told BBC Radio Stoke.
"It's not a situation where someone would elbow someone in the face in all honesty, and Nathan's not that kind of a lad.
