"The inclusion of the Italian teams in this season's Magners League means four extra games and with the Amlin Challenge Cup as well, it is important to be able to give guys a rest and rotate the squad.
"We are also very happy to be able to give these young promising rugby players a chance to prove their worth on the big stage.
