The Glasgow player flew into Munster scrum-half Craig Casey on the ground and was shown the yellow card. But the incident sparked a coming together of several players and Ryan Wilson later claimed to have been poked in the eye.
Glasgow lost the match 27-13 at Scotstoun, conceding two late tries while the Warriors player was in the sinbin.
It was a costly misdemeanor and Danny Wilson said the player held his hands up afterwards.
“Ryan Wilson has been absolutely outstanding for this group, I’ve been so impressed with his leadership on and off the field. His commitment to Glasgow Warriors is phenomenal,” said the coach.
“Having said that, he is the first to admit he made an error and a poor decision when we’re only two points behind with 10 minutes to go. It’s tough enough against Munster when you’ve got 15 on the park and eight forwards.
“He fronted up to the group and apologised. He was devastated after the game. That shows the character of the man and his commitment.
“You want Ryan’s edge, competitiveness and aggression. And every now and then you might get a negative with that. But I don’t think this one was any more than a rush of blood and a bad decision. It cost us and he’s man enough and big enough to put his hand up for that.
“There was a bit of handbags after and on the video there’s certainly a hand that comes across on to the top of Ryan’s head. The camera angle doesn’t show any more than that.
“We’ll leave that with the relevant people to deal with. The Pro14 takes care of that now but I know it has been or is still being looked at. So we wait for news on that.”
The player himself was a little more forthcoming on the original incident and its aftermath.
Speaking to the RugbyPass podcast, Ryan Wilson described it as “a moment of madness” but said he was not the only player who should have been shown the yellow card.
“Their nine dived on a loose ball and I just sort of dropped in and stuck the shoulder in as he was on the floor,” said the Glasgow forward.
“But what was to come after that was rather interesting - a couple of fingers in the eye, an open palm to the face from the Munster guys. None of which got looked at. I think there should have been a couple of other yellows. Mine was the least worse.”
It has been a tough start to the season for Glasgow who have had to cope without their large Scotland contingent as well as a number of injuries. They face Cardiff in Newport on Sunday and will once again be deprived of the services of Leone Nakarawa, their Fijian forward.
“He’s not fit,” said Danny Wilson. “He’s got a knee injury - he came back and was assessed and hadn’t recovered from a previous knee injury well enough. That needs strengthening and conditioning and we’re putting him through that process.”
