SHANNON 8 CORK CONSTITUTION 9, Coonagh
Scorers: Shannon: Try: Stephen Kelly; Pen: Tadhg Bennett
Cork Constitution: Pens: Scott Deasy 3
Shannon, who had Ireland 'A' star Felix Jones in the number 15 jersey, thought they had done enough to win this battle of the Munster heavyweights.
But there was a dramatic finish as the game ticked entered its fifth minute of injury-time.
Shannon lost possession at a ruck, Constitution were awarded a scrum on the home 22 and after a few phases they won a penalty 15 metres from the Shannon line. Up stepped full-back Scott Deasy to convert the kick and make it three league wins on the trot for Brian Walsh's men.
This was a meeting of the third and fourth-placed sides in Division 1A and with so much at stake it was inevitably going to be a close affair.
Munster hopeful Deasy put over a fifth minute penalty for the visitors but Shannon supporters were in confident mood after the lightning quick Stephen Kelly finished off a smart move with a try in the left corner. Out-half Tadhg Bennett was off target with his conversion attempt.
But they suffered a heartbreaking finish and are now eight points adrift of leaders St. Mary's College in the table.
