Fleetwood Town manager Joey Barton has been charged with causing actual bodily harm following a post-match incident in the tunnel at Barnsley on 13 April.
Police say the incident, after the Tykes beat Fleetwood 4-2 in a League One game at Oakwell, left a man with facial injuries.
Barton has previously "emphatically denied" accusations he confronted Barnsley manager Daniel Stendel.
The 36-year-old has been bailed until 9 October.
Barnsley complained to the Football Association and English Football League in April about the incident.
At the time, South Yorkshire Police also appealed for any witnesses with footage of the incident to come forward.
Barton took charge of the team for the 1-0 defeat in their pre-season friendly away against Port Vale on Wednesday night.
