The spotlight is back on Munster tomorrow when Cork C of I's potential to win the Irish Senior Cup will be tested by Corinthians's visit to Garryduff in the third round of the Nissan-sponsored competition.

For the past few seasons, C of I have been shaping up as vigorous challengers for all-Ireland honours, only to be eliminated, sometimes shooting themselves in the foot. Much depends on Alastair Dunne's fitness - his latest misfortune has been a chipped ankle - but the Ireland player is expected to line out tomorrow to establish midfield dominance.

Corinthians, of course, will be treated with respect, not only for their dismissal of Lisnagarvey last season but for their current high rating in Leinster circles in which they have the best defensive record and are dangerous on the break. Colin Stewart may find, though, that even if he darts free of one of the Burns brothers, Ger or Karl, the other will still be barring his way and there will be Wesley Bateman, as well, to beat between the posts.

Stewart's fellow Commonwealth striker, Graham Berry of Railway Union, will be a marked man, too, if Annadale have done their research on their Dublin visitors who have also been galvanised by the transfer of goalkeeper David Staniforth from Belfast.

This will be one of the best games among the 10 ties taking place in Ulster where Pembroke Wanderers will need to be at their sharpest to come away successfully from Cookstown.

It will be interesting to see if any of the six surviving second division teams can make further progress. Certainly, resurgent Antrim should not be under-estimated by Three Rock Rovers, though if Liam Canning travels for the Dubliners, the former international could outscore the home side's top marksman, Alan Kelly.

Leinster's only lower ranked survivors, the Mauritius Cup champions UCD, face a formidable assignment at Banbridge where the Co Down side - top of Section One in Ulster - will be determined not to suffer a repeat of last year's shock defeat by Trinity.
