Armagh captain Kieran McGeeney will miss Sunday's Allianz National Football League game against Donegal at Ballybofey.

The 2002 GAA Footballer of the Year sustained a hamstring injury in Armagh's win over Cork on Sunday and could be out of football for three weeks.

Meanwhile, Tyrone boss Mickey Harte has several injury worries to contend with ahead of Sunday's Allianz National Football League game against Dublin at Parnell Park.

Harte already has to plan without his seven Errigal Ciaran panellists while Cormac McAnallen will definitely not be risked against the Dubs because of injury.

Of even greater concern is the shoulder injury which Stephen O'Neill picked up in the win over Galway on Sunday.

O'Neill and half-back Ryan McMenamin were forced to leave the field before half-time in the Pomeroy contest.

McMenamin picked up bruising to his knee and is likely to be available for the Parnell Park game.

However, O'Neill's injury is causing concern within the Tyrone camp.

Thigh and foot injuries forced Declan McCrossan and Ciaran Gourley to depart the fray against Galway but both should be fit for the Dublin match.

Chris Lawn came on as a substitute against Galway and could start on Sunday as his groin injury has healed.

Meanwhile, Down defender Alan Molloy is likely to be out for several weeks after pulling a hamstring in Sunday's defeat by Mayo.

With Ciaran Byrne suspended and Brian Burns injured, Down may be forced to deploy either John Clarke or Liam Doyle in the number three role against Sligo this weekend.

Dunloy concerns

Midfielder Gregory McCartan will be ruled out of the next two games against Sligo and Laois after receiving a straight red card against Mayo.

Meanwhile, Errigal Ciaran's Peter Canavan and Dunloy hurler Gregory O'Kane have been selected as the AIB players of the Ulster Club Championships.

The duo will receive the rewards, with the other six provincial winners, at a function in Dublin on 3 March.

Meanwhile, Dunloy hurlers have injury concerns over Liam Richmond and Damien McMullan ahead of Sunday's AIB All-Ireland Club semi-final against Waterford side Mount Sion.

Richmond has missed a number of challenge games over the last month because of an ankle injury.

He did take part in a run-out over the weekend but remains doubtful for the Mullingar contest.

Peter Canavan: AIB club winner

McMullan has a thigh injury and Dunloy are unlikely to decide on their fitness until later this week.

On the plus side, Gary O'Kane who was troubled by a hamstring injury in the latter part of last year is fit again while Malachy Molloy has also recovered from rib damage.

Mount Sion have minor injury concerns over Tony Browne, Michael White, Anthony Kirwan, Roy McGrath and Brian Greene but all are expected to start.

Allstar forward Eoin Kelly is also in the frame for selection despite apparently having a row with the club's management a fortnight ago.

The Mount Sion line-up also includes another current Allstar Ken McGrath.

Meanwhile, the practice of GAA players making weekend trips to play for New York clubs is to be ended.

The New York county board took the decision at its annual convention over the weekend.

Tightened immigration controls have made it harder for players to gain entry to US while the New York board also feel that the influx was affecting the development of young talent in the Big Apple.
