Cilliers will join Irish as they bid to return to the Gallagher Premiership at the first time of asking following their relegation last season.

Irish director of rugby Declan Kidney said: “The Championship is a tough league and we need experienced forwards in our squad to meet the challenges in front of us.

“Pat fits the bill – he’s played at the top level of the sport for a number of years and will be a good signing for us.”

Cilliers could return to Welford Road for the pre-season fixture against Irish on Friday, August 24. The game is included on the Tigers season ticket and match tickets are now available. Click below to book your place.
