Down have named Danny Hughes in their line-up for Saturday's All-Ireland SFC qualifier against Clare but the forward is not expected to start.
Hughes sustained a hamstring injury in training on Wednesday night.
If Hughes is ruled out, the Down team will show four changes from the Ulster defeat by Armagh.
Aidan Brannigan and Kevin Duffy replace Daniel McCartan and Gerard McCartan in defence with Conor Laverty in for John Clarke who has quit the panel.
Gerard McCartan is among a number of defenders ruled out by injury.
The Down subs have not been announced but Caolan Mooney is expected to be included included in the Mournemen's squad of 26 for the match.
Mooney is still a Down minor but his performances in training and challenge games have obviously impressed the county's management team.
Long-term casualty Ambrose Rogers is making good progress from a knee injury but is unlikely to face Clare in Ennis.
Meanwhile Antrim manager Liam Bradley has named the same starting line-up which lost to Donegal in the Ulster SFC preliminary round for his side's qualifier against Westmeath.
Kevin McGourty and Andrew McClean were unavailable while James Loughrey, who has returned to the squad after being out because of exam commitments, is named in the substitutes.
Crusaders soccer goalie Sean O'Neill will again be between the posts for the Saffrons.
Antrim were beaten by Donegal in a dismal Ulster Championship opener while Westmeath were beaten by Wexford in the first round of the Leinster Championship.
Westmeath boss Pat Flanagan makes four changes from that game with James Dolan, John Heslin, Micheal Curley and David Duffy replacing Francis Boyle, Paul Sharry, David Glennon and Paul Greville.
Dessie Dolan kicked some glorious points from play against Wexford and remains Westmeath's most potent attacker.
Fermanagh boss John O'Neill has made four changes for the All-Ireland qualifier against London in Ruislip.
Niall McGovern, Richard O'Callaghan, John O'Flanaghan and Niall Cassidy replace injured duo Barry Mulrone and Hugh Brady plus Terry O'Flanaghan and Niall Cassidy.
Fermanagh defeated London by 0-14 to 0-8 in the National League in April but the Exiles will fancy their chances against taking Mayo to extra-time in the Connacht Championship.
London's best known player is Paul Geraghty but they include several other talented performers as the economic crisis caused emigration to the English capital.
The Erne County's season has been badly affected by internal rows with several players making themselves unavailable for action and they then produced a woeful performance against Derry in the Ulster Championship.
Monaghan boss Eamon McEneaney has made three changes in personnel for their clash against struggling Offaly in Tullamore.
With Dessie Mone suspended, Donal Morgan is drafted into defence with Darren Hughes switching from full-back to centre half-back.
Defender Colin Walshe is ruled out by injury so Niall McAdam moves from the attack to wing-back while Christopher McGuinness and Bernard O'Brien are drafted into the forward line with Stephen Gollogly losing his starting role.
McGuinness and O'Brien will both be making their first Championship starts.
Vinny Corey, who missed the narrow defeat by Tyrone because of injury, is included in the substitutes.
Offaly, who were hammered by Wexford in the Leinster SFC, will include talented forward Niall McNamee and experienced Ciaran McManus.
Cavan will be without suspended Ray Cullivan for their clash against Longford at Kingspan Breffni Park.
Mark McKeever replaced Cullivan while Martin Cahill and Thomas Corr take over from Dermot Sheridan and Patrick Carroll in the defence.
Longford won this season's Division Four title and were unlucky to lose against Laois in the Leinster SFC so Cavan's young side - unimpressive against Donegal - will go in as underdogs.
