Team news: Tyrone manager Mickey Harte has left Ciarán Gourley out of the starting line-up for Sunday's All-Ireland football championship fourth-round qualifier against Laois at Croke Park. The corner back has been replaced by Michael McGee from the Lochmacrory club.

The only other change sees corner forward Mark Harte, as expected, coming back in for Michael Coleman, a late replacement for the manager's son against Galway on July 17th.

The team trained in Clougher last night with the only absentee being Colin Holmes, who is a long-term casualty because of a stress fracture of the foot.

Gavin Devlin still has a shoulder injury but it's unlikely he would have been able to dislodge Shane Sweeney such has been the centre back's form since getting his chance.

Last year's captain Peter Canavan is making steady progress and is expected to be introduced before the last 15 minutes - the time of his arrival the last day.

"He still has not played enough competitive football for 10 months," said Harte. "He played a league match last Sunday and the Galway game allowed him to gain a bit of time. Work has been good so if we get a good result on Sunday he will be back in contention for the quarter-finals if not, well that's it."

Harte also weighed in behind several top managers in the country, including Mick O'Dwyer, in criticising the lack of time the defeated provincial finalists had to prepare for the next round of the championship.

Both Limerick and Laois have been forced to regroup for the fourth round in just a week because they drew their respective provincial finals.

"I know it benefits us ahead of Sunday but I don't think it's right," said Harte. "The proviso of a two-week clearance should still be honoured. They should have pencilled in the possibility of draws in the interest of fair play.

"If you are beaten in the provincial final it is unfair to have to turn around so quickly and legislation should be brought in to change it."

The GAA brought in the stipulation of a minimum 13-day break for the provincial losers this year but never factored in the fixture congestion caused by replays.

In Laois, O'Dwyer has put off naming his team until tonight to allow their walking wounded a chance to heal.

Darren Rooney is all but out as he still has a cast up to his elbow because of a broken thumb but the stance on All Star Tom Kelly's availability (finger injury) is more promising.

It also emerged that Martin Delaney also absconded from the panel, along with Colm Byrne and Michael Lawlor, after last weekend's defeat to Westmeath. However, like the other two, he showed up for training on Wednesday and was allowed rejoin his team-mates.

Everything appears to have been resolved but with only eight days to prepare for the knockout match against the All-Ireland champions the scars of unrest may have a longer lasting effect.

Meanwhile, Dublin have again resisted naming a side until the day of the game. Everyone is fit except Colin Moran who broke his arm in a challenge match against Limerick.

A likely change could see Shane Ryan coming in at wing back for Paul Casey, while Dessie Farrell is expected to remain on the bench, with Ian Robertson again providing a high-ball option at full forward.

"It's great to see Ian back enjoying it," said Farrell. "He has been plagued by injuries but is getting a clean run now. He is very passionate about the game and his level of experience and composure was needed. His return has been invaluable."

The return of Farrell and Robertson has been an obvious boost for Dublin and did a lot to alleviate the intense criticism that Tommy Lyons was receiving. It also showed that the greater good of Dublin football was the priority of the management and players.

"We're going fine at the moment. The work is done now," Farrell continued.

"Public opinion has Dublin's summer written off and not too much is expected due to the manner of the defeat to Westmeath. Also, we didn't look like world beaters against London, Leitrim and Longford but there is never such a thing as a low-key build up in Dublin."

Clare and Kilkenny are also remaining tight-lipped regarding their sides for tomorrow's hurling quarter-final replay in Thurles. Brian Lohan, whose participation in the championship has been hindered by hamstring troubles, is expected to be named among the substitutes.
