Leinster Rugby head coach Leo Cullen has issued an injury update ahead of Friday’s Guinness PRO14 Rainbow Cup game against Ulster Rugby at the RDS Arena (KO 8.15pm – live on eir Sport and RTÉ Radio).

Both Jimmy O’Brien (hamstring) and Caelan Doris (calf) hope to resume full training this week after recovering from their respective injuries and, provided all goes well, both hope to be available for selection for Friday’s game.

Jamison Gibson-Park will continue to be managed this week with his hamstring injury while Jack Conan, who went off for a Head Injury Assessment against Connacht Rugby, will follow the Graduated Return to Play Protocols this week.

Unfortunately, Ciarán Frawley injured his shoulder and his hamstring against Connacht Rugby and will be unavailable for selection this week with further assessment required on his injuries.

There was no new update on a number of players: Rhys Ruddock (calf), Harry Byrne (hamstring), Johnny Sexton (concussion), Will Connors (knee), Jack Dunne (ankle), Adam Byrne (quad), Dan Leavy (knee), Conor O’Brien (knee) and Max Deegan (knee)
