Cork Con will be looking for a return to the play-off places when they take on Lansdowne at the Aviva Stadium in the Ulster Bank League Division 1A tomorrow (2.30pm).
Con were humbled in a 20-8 defeat at home to Terenure last weekend with Darren Sweetnam's try the only positive. That loss, coupled with Ballynahinch's 18-16 victory over UCD, saw Con drop to fifth.
It doesn't get any easier this time as they face the league leaders who have won 12 of their 15 games and beat Old Belvedere last weekend.
Elsewhere, Dolphin must win as they take on reigning champions Clontarf at Castle Avenue.
The Corkmen are bottom, eight points behind Old Belvedere and with time running out - Dolphin lost 24-9 away to Young Munster last Saturday.
In 1B, Garryowen are just one point behind leaders Galwegians going into their game away to Ballymena at Eaton Park tomorrow. The Dooradoyle outfit clinched a bonus point in their 37-14 win over UL Bohemians last weekend.
There is a relegation derby as UL Bohs host Shannon at Thomond Park tonight (7.30pm).
In 2A, Cashel host City of Derry, Nenagh Ormond are home to Skerries, Thomond host Rainey OB, while UCC host Seapoint.
In 2B, leaders Highfield are away to Richmond, Sunday's Well host Midleton, Bruff are home to Kanturk, and Old Crescent welcome Greystones to Rosbrien.
