With their Wales stars out in Poland preparing for the autumn internationals, the regions are calling upon some of their up-and-coming talent this weekend, in another round of PRO12 games.
Cardiff Blues - who were thrashed by Leinster last time out - welcome fellow Irish heavyweights Munster to the Arms Park tonight. The Dragons travel north to face Glasgow, who have won their last five PRO12 matches.
Tomorrow, the Scarlets host the league's bottom side, Zebre. On Sunday, reigning PRO12 champions the Ospreys face Leinster at the Liberty Stadium.
