The weekend's events hardly make good reading for Ulster interest in the division as both Ballynahinch and Ballymena ended up on the wrong end of their results against Naas and UL Bohemians respectively.
Hinch were at home but tumbled badly to Naas who triumphed in a high-scoring 41-24 game which saw a total of 10 tries - six of which were scored by the victorious visitors.
After this second successive defeat for the Co Down side there is now a pressing need for coach Derek Suffern's squad to pick up a win when they travel to struggling Galwegians on Saturday.
"We gave them (Naas) cheap scores early in the game and they had Fionn Carr and Johne Murphy who made a difference," said a clearly disappointed Suffern.
"We did get back to 14-14 and then they scored from long range. We were 12 down but we still thought we'd be ok but then they scored from a long range intercept.
"So they kept scoring off our mistakes and we weren't really good enough on the day to be honest."
That Hinch did manage a try bonus allowed them to at least take something from the game but, in reality, this was little comfort to the Co Down side who fell a place to sixth.
They started well enough with a Sam Windsor try and conversion, but Naas then came back to take the lead with two tries. Hinch, though, gathered themselves and drew level after David Nicholson got over in the corner with Jonny McPhillips converting.
But then it all went south as four more tries from the visitors saw them stretch their lead out to 38-14. The Co Down side did, at least, get over for two more tries which were supplied by David Busby and Kenny Morton got the bonus score, but trailing 38-26 was as close as Hinch's revival got and the Co Kildare side finished the day with a penalty and have now moved to fourth.
Meanwhile, Ballymena became the latest victims of leaders and still unbeaten UL Bohemians, the Munster side prevailing 25-15 on the artificial surface at the University of Limerick.
The Braidmen - who have now fallen two places to fifth -only trailed 17-15 at the break, with their tries being scored by Jonny Rosborough and Rodger McBurney, but they didn't score again after the restart.
