Scunthorpe United have asked for help identifying supporters who threw coins on to the field of play during Friday night's win over Wycombe.
The coins were aimed at Wanderers goalkeeper Talia, who some sections of the terrace felt was feigning an injury after a challenge with Iron striker Paul Hayes.
The incident was included in the referee's match report, and could see the club fined.
Fans with information are asked to call Safety Officer Alan Webster on 01724 848077, with calls handled in the strictest confidence.
A statement said: "Scunthorpe United would like to stress that any individuals caught throwing missiles on to the field of play will face exlusion orders from the ground."
