David Young has also sent out a message of thanks to the supporters who have organised three official coaches to travel to Swansea for the match plus the many other fans who are making their way independently.
He said, "With six matches to go everything is in the melting pot for at least three and probably four of the Welsh regions and we are due to play not only the Ospreys but also the Dragons and the Warriors on their own grounds in the weeks ahead. Support like what we are expecting this weekend is marvellous and all the team appreciate it."
