The last thing you expect on a basketball court is to be punched in the face by a team-mate, but that’s exactly what happened to Nikola Kalinic┬áduring a EuroLeague clash.

Former NBA player Pero Antic reacted in sudden and aggressive fashion following a player under the basket as Anadolu Efes faced Fenerbahce.

Antic, who plays for Fenerbahce, accidentally punched Kalinic flush in the face with his reaction – and it looked incredibly painful.

A stunned Kalinic reacted with understandable shock as he confronted his team-mate to question what on earth happened, with Antic having to simply shrug and apologise.

“Oh my goodness!” cried the commentator.

Thankfully, Kalinic was okay besides a likely bump on the head.
