Arsenal manager Arsene Wenger apologised for the challenge by captain Cesc Fabregas which led to Wolves defender Stephen Ward being carried off on a stretcher during the Gunners' 2-0 win at Molineux.
Ward suffered a gashed leg in the mistimed touchline tackle by Fabregas during the closing stages of the second half.
The Spain midfielder escaped with a yellow card and then rubbed salt into Wolves' wounds by setting up Marouane Chamakh's second goal of the game in the closing seconds.
Fabregas also made a point of saying sorry to Ward after Arsenal bounced back from their shock home reversal by Newcastle.
Wenger said: "I think it was an accidental tackle. That's what Cesc told me. He touched him (Ward), of course, but he wanted to play the ball. He went to the dressing room and apologised to the player and it is all right.
"I have not seen the tackle yet but I have just apologised to (Wolves manager) Mick McCarthy if the player is injured. I didn't know exactly what had happened because the linesman was in my view. Fabregas said to me it was completely accidental but he still went to see the player to see how badly he was touched. It doesn't mean if you go to see how the player is, that you feel guilty."
