All-Ireland League: After four rounds of the AIB League Division One, UCD are the only team unbeaten after Garryowen were undone by an injury-time try from Belfast Harlequins' Johnny Lowe in Dooradoyle on Saturday.
It was a weekend for late revivals in the league as both Blackrock College and Buccaneers also salvaged victory in the final furlong.
Buccaneers flanker Eoin Brennan crossed for an injury-time try to tie up their hotly contested match against bottom club Co Carlow at Oak Park. Full back Justin Meagher then stepped up to earn a 23-21 victory to cancel out a remarkable kicking display from Carlow outhalf Richie Murphy.
In Dublin, Blackrock trailed 17-16 with 10 minutes remaining but tries from Andrew O'Neill, his second of the afternoon, and Dave Dillon helped them overcome Ballymena.
O'Neill and opposite number Andrew Trimble, who also grabbed a brace of tries, were superb but it was the reliable boot of 'Rock's Conor Kilroy that really made the difference.
