Justin Sherriff will be much closer to full fitness after making his long-awaited comeback from injury in the weeks before Christmas while Colin Kelly has greater availability after a busy work schedule kept him away from hockey before Christmas.
Instonians, meanwhile, have hit form in recent weeks with international duo Mark Gleghorne and Steven Redpath back after long lay-offs, following Patrick Brown back into the team. Their return has freed up Mark Irwin to move further up the pitch and he prospered last week with a hat-trick against Bangor in a 5-1 win, adding to two goals against Mossley. Mark Wainwright, however, is out of David Scott's selection.
In an effort to guarantee the game is played, Queen's University have reserved a pitch for Sunday should Shawsbridge be frozen. The three-day forecast currently sees six to eight degree temperatures in Belfast, though, so hopes are high the game will be completed.
