Former Cavan GAA star and current MDL Oscar Traynor representative player Michael Brennan gave OMP the lead with a well-taken goal after 25 minutes. But they failed to capitalise on their lead, and Kevin McAvinchey scored a deserved equaliser for Fordrew with 20 minutes remaining.
Some other Premier Division fancied sides fared out better. Quay Celtic ran riot at home to Bailieboro Celtic where they hit them for 11.
Mark Savage scored four, Barry Walsh got two, with further goals from Barry Carr, Barry McKenna, TJ Murtagh, Derek Moran and an OG.
Navan Cosmos won 7-1 at home to Torro United where Lee Duffy and Laurence Ivors both scored hat- tricks, with the other goal coming from Conor Walsh.
Duleek defeated Abbey Celtic 4 -1, and Trim Celtic were victorious by 3-0 against Athboy Celtic.
The current holders Kingscourt Harps kept the hopes alive for another division two success in the competition, winning 3 -2 away to premier side Bellurgan, where Darren McCabe, Danny Hand and Cathal Connolly all scored.
Bellurgan replied through Shane Finnegan and Darren Gaynor.
The holders of the O'Neill Shield, Bohermeen Celtic, could be heading out of the competition following a 0-1 loss away to Kilmessan. They require the other team in the group, Rossin Rovers, to secure a win against Kilmessan to keep the group alive.
Last season's runner up, Laurence's FC, won 6 -4 at home to Rathkenny. The derby involving Ballyjamesduff United and Ballyjamesduff Celtic ended at 1-1.
