St Vincent's (Dublin) 0-16 Palatine (Carlow) 0-08
Diarmuid Connolly was dismissed at Netwatch Cullen Park as AIB All-Ireland club title favourites St Vincent's laboured to a 0-16 to 0-08 victory over Palatine to advance to the Leinster semi-finals.
Dublin's All Star attacker was shown a black card following a first-half grapple with Palatine's Shane O'Neill, though his team weren't made to pay.
Cormac Diamond rose to the occasion in Connolly's absence with a man-of-the-match display, scoring five important points and having a direct hand in three others.
Veteran free-taker Tomas Quinn improved as the game wore on and contributed five points too, though it was another game where Vins did just enough to progress.
They were tipped to win by a double-digits margin, but were just two ahead at half-time and only pulled clear in the last 20 minutes.
The 2008 and 2014 All-Ireland champions had also recorded relatively narrow wins over Castleknock, Ballymun and Lucan in the latter stages of the Dublin championship.
They hinted early on at running amok as they strode four points clear after just five minutes.
Diamond kicked a brace of points and Enda Varley, the former Mayo attacker, and Shane Carthy were on the mark.
But the scores surprisingly dried up for Tommy Conroy's men after that, with 21 minutes passing until their next point.
In that period, O'Neill and Jamie Kenny got Palatine off the mark with points to leave the underdogs just 0-04 to 0-02 down.
Connolly got his marching orders in the 19th minute after an umpire drew referee Niall Ward's attention to an incident between the Dubs star and O'Neill.
Connolly actually clashed with O'Neill twice in separate incidents and it appeared he was sanctioned for the first.
Joe Feeney, who played for Armagh in the championship this year, wasn't a bad replacement.
Diamond's third point for Vincent's in the 26th minute finally broke their scoring duck, but it remained a poor contest with the visitors registering eight first-half wides.
Vincent's led 0-05 to 0-03 at the break, with O'Neill, Palatine's best player, scoring two of those points.
Four points were evenly split between the teams after the restart, but Vincent's eventually took control from the 40th minute to win at their ease.
The Marino outfit scored five points without reply between the 41st and 49th minutes, three of those coming from Quinn, to put the result beyond doubt.
Vincent's used their full allocation of subs and there were impressive cameos from Albert Martin, who pointed with his first touch, and Kevin Golden, who won a free for Quinn to convert.
