An Argentina hockey player hit his opponent in the head with his stick to spark a huge fracas in their Olympics clash against Spain.
In what was a bizarre incident, Lucas Rossi purposely tapped David Alegre in the head while he received treatment for cramp.
Rossi was furious, obviously believing his opponent Alegre was faking an injury to waste time.
The 36-year-old shouted in his face before jabbing him in the head with his stick.
It sparked a scuffle between both sets of players, who began exchanging verbals before Rossi was ushered away by his teammates.
Shortly after, the referee brought the match to a close with the scoreline level at 1-1.
Elsewhere at the Games, Adam Peaty underlined his status as the overwhelming favourite to become the first British swimmer to retain an Olympic title by cruising into the semi-finals of the men’s 100 metres breaststroke.
The 26-year-old from Uttoxeter prevailed in his heat in 57.56 seconds at the Tokyo Aquatics Centre, the quickest time of anyone to compete in the event on Saturday night and the eighth fastest of all time over the distance.
He owns the previous seven as well and attention in Sunday morning’s semi-final will turn to whether he can set a new world record, currently 56.88secs which he recorded en route to winning gold at the 2019 World Championship.
