Munster and Ireland were given a big boost last night when Marcus Horan returned to action after a lengthy spell of injury.
The loose-head played for 51 minutes in the battle of Limerick arch-rivals Garryowen and Shannon, in this Ulster Bank AIL clash but his side went under to a revitalised Garryowen, who put their poor form behind them.
Declan Cusack had Garryowen in front with penalties after five and 17 minutes.
Shannon suffered a setback when top points kicker Tadhg Bennett had to retire injured after only 10 minutes and they suffered another blow when Kevin Griffin was sin-binned after 28 minutes.
Bennett's replacement Gareth Quinn-McDonagh landed a penalty after 39 minutes and just on half- time Stephen Kelley scored a try to have the visitors 8-6 in front.
However, Garryowen dominated the second half, with tries by Alan Gaughan which Cusack converted and Paul Nevile stormed over for another. Mick Sherry added a third on 62 minutes which Cusack again converted.
Shannon never gave up and a try two minutes from by Les Hogan two minutes from the end was fitting reward for the prop.
