Fans will get the chance to say goodbye to Jason Robinson

Premier Rugby, which represents the 12 Premiership clubs, says players cannot be released as the weekend is already allocated for EDF Energy Cup fixtures.

"Playing one-off fixtures like that in the season isn't feasible," said Premier Rugby chief Mark McCafferty.

The Barbarians squad will include Jason Robinson, Matt Giteau and Chris Latham.

Martyn Williams, Jerry Collins and Sitiveni Sivivatu have also been included in the pre-match advertising for the 1 December fixture.

South Africa are expected to tour with a star-studded squad including the likes of Bryan Habana, Victor Matfield, Schalk Burger and Percy Montgomery.

McCafferty said he was unhappy that the Barbarians had attempted to contact players at English clubs directly after already being informed of Premier Rugby's position.

"I'm not surprised they've approached players, but I'm disappointed because they came to us centrally and we gave them the clear position that the board of the Premiership had confirmed," he said.

"It's disappointing if players have been approached when that is the case but we still expect the clubs to support the position."

We have no stake or interest in the game Premier Rugby chief executive Mark McCafferty

The Barbarians match clashes with the final weekend of group matches in the EDF Energy Cup, which all 12 Premiership clubs take part in.

McCafferty added: "They have to understand that during the season it is not possible these days. We have no stake or interest in that game.

"Our message to the Barbarians has been for some time that we are very willing to work with them on post-season games during the summer, but it's very difficult, if not impossible, for us to release players during the season for those sort of representative fixtures

"It's an EDF Energy weekend, one they are committed to. As far as the clubs are concerned the communication to the Barbarians has been that we cannot and won't release players for that game.

"We've had a number of discussions with the clubs over the last few weeks and are not expecting any of the English players to be released. They have enough pressures in terms of their club commitments.

"We do recognise the great cause of the Barbarians, the brand and the charitable causes they support.

"And we are prepared to work with them on the end-of-season games they traditionally have and on some of the tours they do - but they have to understand that during the season it's not possible."

The Barbarians, founded in 1890, are an invitational side comprised of stars from all over the globe.
