Canning suspension costs Portumna
The absence of the suspended Joe Canning and Andy Smith proved costly as three-time All-Ireland club champions Portumna were sent crashing out.
Portumna, who had only lost three of their previous 41 championship games in Galway, were ousted by St Thomas in a gripping contest at Ballinasloe.
A goal just before half-time from inter-county midfielder David Burke proved key as St Thomas reached their first county semi-final in 22 years.
The accuracy of Davy Canning from dead balls kept Portumna in touch, but Galway U-21 forward James Regan came to the fore with three points in the final eight minutes which saw St Thomas into the last four on a 1-10 to 0-12 scoreline.
Defending All-Ireland champions Clarinbridge needed three late points to force a replay against Mullagh in Athenry.
A Paul Coen goal after four minutes gave Clarinbridge a 1-6 to 0-4 lead, but a sizzling start to the second half saw Mullagh lead by a point with seven minutes left.
Points from Davy Glennon and Finian Coone looked to have killed off Clarinbridge, but a score from Coen and two Mark Kerins frees edged them back ahead, only for Coone to clinch a deserved draw for Mullagh with the last puck of the game.
Goals from Ollie Fahy and Keith Killilea saw Gort also reach the semi-finals as they beat last year's losing finalists Loughrea.
And Craughwell booked their place in the last four with a 0-19 to 0-11 victory over Carnmore thanks to a late burst.
