Delon Armitage has admitted that he was "stupid" to mock Brock James as he scored a try in Saturday's Heineken Cup final.
Armitage's actions sparked criticism from players and fans alike.
Former England hooker Brian Moore wrote on Twitter: "If a player did to me what Armitage has just done, I'd have to chin him after the touchdown."
Armitage then exchanged an online war of words with Moore, but has now accepted that he was in the wrong.
"It was stupid celebrating before [scoring], but I was just so happy to score in a Heineken Cup final," Armitage told The Telegraph.
"It was a dream come true. I knew straight away that I was going to score. There was no-one in front."
Toulon had never previously competed in a Heineken Cup final.
