Ballyclare have to upset the odds to see off Instonians
Instonians are the holders of the White, McCall Wylie Junior Cup and with only one early season defeat to mar their record, should be too strong for Ballyclare in the quarter-finals.
"Our performances have improved from week to week and we have been fortunate to have been able to rotate our squad in the past few weeks," commented coach Wilbert Leacock.
"Rory Bell has returned after injury and has performed well while Richard McCarthy, who was at out-half in the 52-35 win over Hinch, has put his hands up for selection."
That disappointing effort at Clogher Valley spurred Inst on to a win over league leaders, Bangor, and they have been on the up ever since so Ballyclare with only four wins from seven outings will start as underdogs.
Clogher Valley face Portadown for the second time in nine days.
Last season's defeated finalists, Omagh, entertain Dromore but both have a poor league record with only two successes from their five games.
Omagh have the advantage of having already defeated their opponents 22-17 but that was in the first game away back in August. Bangor are vying to be the top Junior team but face a difficult hurdle against Ballynahinch II at Upritchard Park. This tie starts at 2 pm, the others following 30 minutes later.
