Young Munster 6
Cork Constitution 3
Young Munster caused a big surprise when they defeated table-toppers Cork Constitution in a low-scoring but lively affair at Tom Clifford Park.
A penalty by Gerry Hurley after 32 minutes had Con in front by the only score of the first half. When Stephen Archer was sin-binned for the visitors after 67 minutes, it afforded Alan Kingsley the chance to kick Young Munster's first penalty and he clinched the win after 75 minutes with another penalty.

OLD BELVEDERE 10
BLACKROCK COLLEGE 9
DAVE Mongan's late try and Andy Dunne's subsequent conversion moved Old Belvedere back to the top of the table at Anglesea Road.
Struggling Blackrock looked in a good position to take the Dublin derby spoils after Rob Keogh's three penalties to Conal Keane's single effort.
But the hosts kept going and their patience was finally rewarded as the prolific winger crossed with just three minutes remaining.
Dunne added the conversion to help his side leapfrog Cork Constitution.
Scorers -- Bective Rangers: G O'Grady 3 pens. UCD: T Fletcher, M Toomey try each, J Thornton 2 pens
A last-minute try helped Buccaneers past Clontarf in a top-of-the-table clash at Dubarry Park. An Adam Kennedy penalty after 11 minutes was the only score in a dour opening half.

Full-back Brendan Deady scored the only try as Bruff edged out UCC at Kilballyowen. A penalty by Brian Cahill had the home side in front at the interval.
UCC rarely looked like getting a try. And when Deady and Eoin Maher linked up twice before the former got over it put the issue beyond doubt.
Scorers -- Bruff: B Deady try; B Cahill, pen, con
