Coaches from both dugouts were sent off during Wigan Athletic's win at Newcastle United.
Callum McManaman's first-half lunge at Massadio Haidara saw the French defender taken to hospital with suspected knee ligament damage and led to Newcastle coach John Carver being sent off at half-time for trying to get to the Wigan player as the teams left the field.
Wigan coach Graham Barrow was also dismissed by referee Mark Halsey for his part in the melee.
