MUNSTER BOSS MIGHT ALLOW IT TO PETER OUT.

JOHANN VAN GRAAN won't risk Peter O'Mahony if he's not fully fit to face Leinster - despite insisting Munster's only focus is winning to secure a home URC quarter-final.

With first seed status already secured, Leinster will play their second-string as they continue their Champions Cup final build-up but Munster need to go full tilt at the Aviva.

While guaranteed a play-off spot, the Reds could fall to sixth and out of the top seedings depending on results this weekend.

Two of their best backs, Damian de Allende and Simon Zebo, are definitely out for the derby clash with chest injuries.

"I'm not even going to put them in that position," said van Graan. "They won't recover in time."
