Two former Munster players are among the Irish contingent at RFU Championship club Ealing Trailfinders - the team who will be the first to take on Saracens since they were relegated from the Premiership for repeated salary cap breaches.

The Trailfinders Challenge Cup, which is completed by Doncaster Knights, is a round-robin competition that will take place over six weeks and serves as a curtain raiser to the Championship.
