Bournemouth manager Gary O'Neill was baffled after Crystal Palace defender Joachim Andersen received no punishment for appearing to hit Jefferson Lerma with a closed fist on Saturday.
The incident occurred during the first half of Palace's 2-0 win at Selhurst Park when the score was still 0-0.
Lerma fell the ground inside a packed penalty area as Bournemouth were defending a corner kick.
Replays showed that Lerma had been struck in the face by Andersen but a VAR review did not result in a red card for the Danish center-back.
Speaking to reporters after the game, O'Neill said: "Andersen punched Lerma in the face, Jefferson has a broken nose."
He added: "It's difficult on the pitch to see that, but I have no idea how VAR can give it as 'check complete'.
"He was in pain, his nose is broken, it was a strange incident. But there are other things I need to talk about."
Eberechi Eze scored both of Saturday's goals as Palace's victory took them to 43 points - level with London rivals Chelsea in the Premier League table.
