O’Callaghan boost as Munster face Ospreys

DONNCHA O’Callaghan looks certain to make his seasonal Heineken Cup debut against Neath/Swansea Ospreys this weekend.

O’Callaghan was ruled out of the opening tie with Harlequins due to a calf strain but is odds on to take his place in the side.

As the Ospreys prepare themselves for their biggest Heineken Cup pay-day, Munster will be further boosted by the availability of Shaun Payne.
