Sam Allardyce was caught up in a touchline row after one of his Sunderland players was slammed into a advertising hoarding by Norwich City winger Liam Brady.
In the opening minutes, with the ball running out of play, Brady unnecissarily shoved DeAndre Yedlin off the pitch - the Tottenham Hotspur loanee slamming head-first into the electronic hoarding.
Allardyce and fellow members of his bench immediately leapt to their feet to complain, while players from both sets of teams joined in a melee.
At first the former Bolton Wanderers, Newcastle United and West Ham manager stayed on the fringes, but then got involved when he saw Cameron Jerome, a Norwich substitute, involved in the altercation.
Allardyce pushed him away, then started bushing Brady and others.
