ONE change has had to be made to the Ulster team for Sunday's Railway Cup football semi final against Munster in Clones. The postponement of the match from the original date on January 28th has created a clash with the All Ireland club football semi finals.

Armagh's Kieran McGeeney, chosen at centre back for his Ulster debut three weeks ago, loses out because of his club Mullaghbawn's involvement in the Navan semi final against Leinster champions Eire Og, from Carlow.

He is replaced by Scam us McCallan, another debutant and centre back on the Tyrone side which won the Ulster title and reached last year's All Ireland final, who moves up from the reserves. On to the substitutes' bench comes Armagh's Martin McQuillan who has been a regular feature of Ulster teams during the province's record breaking run of six successive Railway Cup wins.

Derry's Tony Scullion, a veteran of all six victories, is again named in the team. It will be his 13th consecutive appearance in an Ulster jersey and he last lost a Railway Cup match back in the 1988 final against Leinster.

It has emerged that Munster have made an application to have the match postponed again. One difficulty the re arranged match poses; for the southern province is the likely unavailability of manager Paidi O Se who is organising a club tournament in Dingle.

No decision has been made, but it is thought unlikely that Ulster will accede to the requested postponement.

Leinster's selectors will select their team for the other semi final, in Navan against Connacht, tomorrow night. A number of issues will be addressed. Like Ulster, the team, is, affected by the Mullaghbawn Eire Og semi final and Carlow's Colm Hayden, an original selection, will be released to play for Fire Og. Of course, it would be possible for Hayden to play both matches as the Railway Cup match is the second event on a double bill at Pairc Tailteann.

According to Leinster selector Niall Rennick, no decisions have been made on other issues: the suspension of Laois's Tony Maher after being sent off against Clare in a League match nine days ago and the question of re opening the selection on foot of the return of provincial champions Dublin from holidays in San Diego.

Among the Dublin players who featured in last year's Leinster team, Paul Curran faces a similar situation to Tony Maher. Curran was sent off in the Division Two match against Louth, but is unlikely to get more than the minimum suspension of two weeks which would leave him eligible for Sunday. Rennick says that Leinster manager Mattie Kerrigan and fellow selector John Crofton have yet to hear whether Maher's likely punishment will stretch beyond the minimum.

"We have to sit down and talk about all these things," says Rennick.

Meanwhile, midfielder Liam McGrath is ruled out of Tipperary's clash with Cork in the National Hurling League on Sunday. The Burgess man, an under 21 star last year, is recovering from a broken wrist. Tipperary otherwise have a full squad available for selection. Tipperary will select their team after training tonight.
