In a statement, the Blues say "some high-jinks between Ioane and another player at the small gathering at a private residence, resulted in the Blues winger receiving a knock above his eye which was treated with medical glue at a local A&E clinic."
"We were just poking fun at each other. It's not serious and I've apologised to my team-mates and the club," said Ioane.
Blues CEO Michael Redman said the club will check on the incident this week to determine if there were any breaches of team protocol.
