Gormley takes over the left corner back position from Michael McGee, while wily veteran Cavlin is preferred to Enda McGinley at top of the right.
McGee had the chastening experience of running up against Paddy Bradley in last weekend’s thrilling drawn encounter when the Derry striker scored 1-6 in what was a ‘man of the match’ performance, while Cavlin impressed when taking over from the out-of-form McGinley.
Seamus O’Neill, selected at left half forward, damaged shoulder ligaments in the drawn game and will undergo a late fitness test.
Derry will delay in announcing their team until tonight because of an injury doubt surrounding teak-tough defender Sean M Lochhart. He injured an arm in the drawn game and is considered to be doubtful.
Meanwhile, Tipperary introduce two newcomers to the senior football championship arena for Sunday’s Munster quarter final clash with Waterford at Walsh Park and good news for the Premier County is that their two most celebrated forwards Peter Lambert and Declan Browne have been given the all-clear.
The new boys on the block are Declan Fanning from the Killenaule club, who has been selected at right half back and Aidan Fitzgerald of Fethard, who receives his call-up at left half forward.
With Lambert, who was carrying a knee injury and Browne suffering from a leg injury, both coming through fitness tests, the Tipperary selectors have named them in their customary right corner and full forward positions respectively.
With the unfortunate Kevin Mulryan ruled out because of glandular fever, Fergal O’Callaghan and Eddie Hanrahan now form the midfield partnership.
Antrim, who take on Cavan in the Ulster championship at Casement Park on Sunday, have made six changes from the side that lost by a point to Westmeath in last season’s All-Ireland qualifiers.
Regular wing back Geroid Adams, who has sorted out his differences with manager P J O’Hare, is now chosen at right corner back with Colm Brady at full back and Niall Ward at left corner back in what is a new full back line.
Peter McCann, who last played in the 2001 championship when Antrim lost to Derry by a point after a replay, is recalled at right full forward.
Cavan were due to name their team last night, but held off because of injury doubts surrounding Jason Reilly, who has a torn quad muscle and their goalscorer- in-chief Peter Reilly who has a calf strain. Of the two Reilly, is the more likelier to start, when the team is announced tonight.
Darragh Spain and Shane Martin have been left out of the Dublin team to meet Laois in the Guinness, Leinster SHC at Nowlan Park on Sunday. Spain is replaced at midfield by Keith Wilson, while Martin's right corner forward spot has been allotted to Tomas McCrane.
