Bristol have confirmed that hooker Mark Regan has been disciplined after defying his club to skipper the Barbarians on Saturday.
Regan played a key part in the Barbarians victory over South Africa
Regan was warned he would be in breach of contract if he took the field.
And after leading the Barbarians to a 22-5 victory over World Champions South Africa, Bristol have now decided to punish the England star.
"We have had a meeting with Mark and he has been sanctioned," said Bristol chief executive David White.
I do have sympathy for players when they get torn between club and country
Bristol have not elaborated on the nature of Regan's punishment, with White adding: "We now consider the matter closed and will not be making any further comment."
Speaking on Monday, Bristol coach Richard Hill said he felt sorry for players forced to choose in such situations.
"I do have a bit of sympathy for players when they get torn between club and country," said Hill.
Premiership players were forbidden from playing in the Barbarians fixture as it fell outside a designated international weekend.
Sale prop Andrew Sheridan was forced to pull out of the game at the request of his club even though the Baa-Baas claimed he was contractually obliged to play for them.

Bristol wanted Regan to take the weekend off so he could be fit and fresh for their Heineken Cup match against Harlequins on 8 December.
But after leading the Baa-Baas to victory at Twickenham, Regan said he had no regrets about ignoring Bristol's orders.
"It's always worth playing for the Barbarians," said the 35-year-old England forward, who played in the World Cup final defeat against South Africa. "They're a great side.
"I'll report for training at Bristol on Monday and no doubt we'll discuss what happens then.
"I'm fully fit and one of my objectives was to stay fit - and beat the world champions.
"I've played against South Africa five times already this year and this was the first time I've been on the winning side, so it was a case of fifth time lucky."
Bristol, meanwhile, recorded a 13-13 draw against Leeds in Sunday's EDF Energy Cup dead rubber at the Memorial Stadium, a game which saw Regan's rival David Blaney score a try.
"Blaney had a very busy day, he worked exceptionally hard and was one of our best ball carriers," added Hill.
"Regan was just below me in the hospitality boxes and was giving David support, but after he scored his try he shut up. I think he was starting to get a bit worried. That is what Ronnie (Regan) needs, a bit of competition."
Mike Burton, Sheridan's agent and a Barbarians committee member involved in assembling the squad, said last week that, in light of the recent row over availability, changes will be made to the selection process.
He said: "We don't want conflict with anyone. For the sake of good relations in the future we want the clubs to nominate players."
