Lansdowne extend lead despite being beaten by UCD
With four rounds to go in Division 1A, leaders Lansdowne remain in pole position for a home semi-final despite losing 38-31 to UCD at Belfield.
It was a vital result for UCD as they are now just two points outside the play-off spots.
However, with second-placed Terenure College losing at Clontarf, Lansdowne's lead at the top of the table was actually extended thanks to their two bonus points.
USA international Liam Og Murphy's 54th-minute try proved the difference for reigning champions Clontarf in a 16-11 win over Terenure. Fourth-placed Cork Constitution did enough to warrant a 6-3 victory over Young Munster, as Tomas Quinlan came off the bench to land a 70th-minute penalty.
Munster's Rory Scannell dictated matters for Dolphin, his chip through releasing centre Cian McGovern for the only try in their 13-3 defeat of Old Belvedere at Irish Independent Park, in front of Ireland coach Joe Schmidt.
Meanwhile, Galwegians and Garryowen both gained ground in the race for promotion from Division 1B. Despite losing front-rowers Doron McHugh and Ciaran Gavin to early arm injuries, Galwegians showed impressive resilience to beat Ballymena 25-17.
Meanwhile, Dublin University's 10-match unbeaten run was ended by Garryowen at College Park. Out-half Jamie Gavin's late penalty - followed up by a blocked Trinity drop-goal - saw the Light Blues triumph 24-23.
