A back injury suffered by captain Scott Nelson in last week's 18-12 win over Connacht has forced McKee into a reshuffle in his backline. David O’Hara will start at scrumhalf with Chris Cousins moving from fullback to fill the vacant outhalf berth. Chris Watson of Ballymoney starting at fullback.
Bangor centre Jason Morgan has returned from injury to replace Nick Finlay and form a midfield partnership Andy Hodgen.
Paul McKenzie is unavailable for the game, having adopted the player coach role last week, so the versatile Jody McMurray comes onto the bench having been unavailable himself last week.
Gareth McCoy replaces Andrew Kelly in another alteration to the replacements..
