Westmeath manager Pat Flanagan and his Derry counterpart Damien Cassidy have announced their teams for tomorrow's All-Ireland SFC second round qualifier in Mullingar (throw-in 5pm).
There are two changes in personnel for Westmeath to the side which lost their Leinster semi-final tie to Louth by two points.
John Gaffey has been named at full-back in place of Donal O'Donoghue, while former All-Star John Keane slots in at centre-back, in place of DIT student Kieran Martin, with the Maryland clubman moving to an attacking role.
Martin has been pencilled in at right half-forward, in place of the injured Derek Heavin.
Heavin exited the pitch on a stretcher 22 minutes into the Louth match, and has been recovering in the Mater Hospital since then with a serious knee injury.
Dessie Dolan starts his second game in succession for the midlanders, and is flanked by dual star Paul Greville and Denis Glennon in the full-forward line.
Kevin McGuckin returns to the Derry side for tomorrow's trip to Cusack Park, in the only change in personnel to the team which beat Carlow last time out.
McGuckin missed the first round win at Dr Cullen Park due to his wife giving birth to their new baby.
The Ballinderry clubman has been listed at full-back, with captain Gerard O'Kane moving to centre-back and Barry McGoldrick switched to left half-forward.
Emmett McGuckian, who was substituted at half-time in the game against Carlow, is the player to lose out.
