Former Hurricanes and current Scarletts lock Sam Lousi faces a long ban, after punching two Munster players during a Pro14 match in Ireland.
Lousi, who also played for the NZ Warriors in the NRL, was given a straight red card for the incident, which left one player bloodied.
The scuffle broke out when Tongan international Lousi engaged in a minor scuffle with Munster back row Chris Cloete.
Lousi then lost his cool, first hitting first-five JJ Hanrahan in the head with a swinging left-hander and then the face of lock Fineen Wycherley with a right.
The punch on Wycherley made contact, splitting the eye and resulting in a blood bin, shortly after the half-hour mark.
At the time, the scores were locked at 3-3, but Munster went on to win the match 29-19.
Munster flanker Arno Botha was shocked with what he witnessed.
"It's not often you see a guy throw a punch," said Botha. "It's usually handbags.
"He got two good shots in, but we had to adapt to playing 14 players and it worked out in the end."
Scarletts is coached by recently appointed All Blacks assistant coach Brad Mooar.
