Roy Keane is expected to allay doubts about his availability for next Saturday's World Cup game against Holland in Amsterdam by joining the Republic of Ireland squad in Dublin tomorrow morning.

Keane is due to go into hospital today for a scan on the back injury which troubled him during Manchester United's 2-2 draw with West Ham on Saturday.

Irish manager Mick McCarthy described the visit as merely routine, however, and said that he had been assured by the player that he will be available to play against the Dutch. "I have just spoken with Roy and he tells me that he's coming to Dublin on Tuesday," said McCarthy. "It's not a serious problem and I expect him to play." Keane, who is due to start a three-match ban which will keep him out of United's Premiership games against Bradford, Sunderland and Everton, said he was looking forward to linking up with his international team-mates.

"It's always disappointing to have to sit out games when you're fit but I'm lucky in the sense that I still have the World Cup match to look forward to," he said.

Earlier, McCarthy had been reassured by fitness clearances for Matt Holland and Gary Breen. Holland played in Ipswich's win over Sunderland on Saturday, while Breen, who had been suffering from double vision, was on the bench for Coventry's game against Manchester City.

McCarthy will hope that Alan Kelly, Jason McAteer, Damien Duff, Steve Finnan and Dominic Foley will avoid injury in today's First Division programme. Additionally Robbie Keane is due to play a friendly game for Inter Milan today.

Holland's new manager, Louis Van Gaal, who was at Parkhead yesterday to watch some of Rangers' Dutch contingent in action against Celtic, was not quite so fortunate over the weekend.

Manchester United's Jaap Stam damaged a hamstring on Saturday and midfielder Boudewijn Zenden will miss the game after bruising his calf while playing for Barcelona in a friendly against Malaga.

"I gather the Dutch have one or two additional fitness worries and I'm certainly not complaining," said McCarthy. "I'll take any help that's on offer."

Meanwhile, Bohemians expect to be able to confirm today that the first leg of their UEFA Cup first-round game with German side Kaiserslautern will be switched to Tolka Park, on Monday September 11th, with the away leg in Germany on Thursday, September 28th.

Kaiserslautern, drawn at home in the first leg, agreed to the switch. The game was brought forward from Thursday night to Monday night to suit German television interests, as there are five German teams playing in Europe that week.

Providing the television deal can be agreed, Bohemians may gross up to £300,000 for the tie when sponsorship and gate receipts are included.
