Alegre hit out as the man ran towards him from the away team’s bench with the plastic bottle in his hand.
Police were eventually forced to get involved as the referee and his linesmen were surrounded by angry players after the clash.
TV footage showed Alegre initially bringing out a red card after one of his linesmen pointed towards the Magdalena bench.
The referee managed to keep hold of the red card in his left hand as he kicked out at the onrushing coach.
The game was suspended after the incident. It was not immediately clear if the man kicked in the face had needed to be taken to hospital or whether he and the referee would face any disciplinary action.
