Mick McCarthy has apologised for his outburst towards West Brom midfielder Paul Scharner after Sunday's derby at the Hawthorns.
McCarthy claimed Scharner was "taking the p***" after he held up his match shirt and displayed a message under his shirt in the closing stages of Albion's 2-0 win.
The Wolves boss has since discovered the message was a Baggies crest and the words 'West Bromwich Albion' drawn on by Scharner's son.
"I'm sorry I even got involved in that because Scharner played well," McCarthy said.
"There was a lot made of it before I even knew what was on the shirt. Having found out there was a West Brom badge on it, I thought 'What the hell?' and it didn't bother me.
"People forget sometimes that I've been a player, and when someone does that to you when you're hurting, those are the kind of things that upset you."
