Cork have been dealt a blow with the news that Alan Cadogan is to miss the remainder of the Munster Championship at least after undergoing surgery on damaged knee ligaments.

The Douglas man sat out the opening-round win over Clare last week, after being described as "50-50" to play, but manager John Meyler confirmed to RTÉ Sport that he has had an operation and is looking at a lengthy rehabilitation.

"We'll have to plan without him for the Munster Championship unfortunately," Meyler said.

Cadogan scored 1-10 from play in Cork's run to the All-Ireland semi-final last year, including 1-04 in the Munster final victory against Clare.

Just last week, Alan had told RTÉ Sport of his excitement at the prospect of playing alongside older brother Eoin, who has rejoined the Cork hurlers after a spell concentrating on football.

Meanwhile, Robbie O'Flynn will sit out this weekend's trip to Semple Stadium but may be back in contention to face Limerick on 2 June.

The forward left the field in a neck brace after a nasty collision with team-mate Conor Lehane in Pairc Ui Chaoimh on Sunday. He was diagnosed with concussion and released after spending the night in hospital.

Meyler said that O'Flynn had "recovered fully but obviously won't be back this weekend.

The Cork boss added that O'Flynn was "under supervision" and medical advice would determine whether he was ready to face the Treaty County.
