Jean Kleyn and Mike Haley have begun graduated return to play programmes following head knocks sustained in Munster’s Guinness PRO14 victory at Connacht last Saturday, the province has said.

Munster lock Kleyn was removed from the field of play after 15 minutes of the 16-10 victory over their Conference A rivals at the Sportsground in Galway but failed to return from a Head Injury Assessment while full-back Haley completed the full 80 minutes.
