Jason McGuinness headed an injury-time equaliser for Shamrock Rovers, who staged a last-gasp rally to earn a share of the SSE Airtricity League spoils drawing 1-1 with Limerick at Tallaght Stadium.

The visitors had Barry Ryan sent off in stoppage time and although Shane Tracy saved a Sean O'Connor penalty, McGuinness levelled with a header from the rebound.

Limerick hit the front in the 14th minute when Rory Gaffney headed home Tracy's inviting free-kick. And there was drama after the restart when Rovers were awarded a controversial 64th-minute penalty, but Barry Ryan saved Gary McCabe's spot-kick.

Rovers were eager to make a positive start and McCabe's clever third-minute cross found Ciaran Kilduff, who headed wide under pressure.

Limerick were set up to be solid as Prince Agyemang, Shane Duggan, and Jason Hughes were busy in the centre of the park.

Despite the visitors’ admirable work ethic, Rovers were still manufacturing chances as Marty Waters shot wide from an awkward angle in the 12th minute.

But Stuart Taylor's side made a trip into Rovers territory count two minutes later as Gaffney glanced Tracy's delivery past Barry Murphy.

Seeking an instant response, Rovers came close to equalising in the 18th minute, but Limerick custodian Ryan got down well to deny a stinging McCabe attempt.

A Waters corner was met by a McGuinness header in the 25th minute, but Ryan gathered safely as Limerick continued to battle impressively.

Gaffney, who remained a threat, slammed a 20-yard shot narrowly wide in the 37th minute just to give the locals' another glimpse of his potential.

After the restart McCabe fired a free-kick over and Trevor Croly summoned Karl Sheppard from the bench to inject further urgency into the Hoops attack.

Rovers were given a 64th-minute penalty when referee Rob Rogers controversially deemed that there had been a handball in the area by a Limerick defender.

Following a lengthy debate Ryan saved McCabe's spot-kick and Limerick eventually cleared the danger.

Then Limerick goalkeeping coach Eddie Hickey was ordered from the technical area moments later as the visitors were incensed following the penalty decision.

And they were equally annoyed at the end when Ryan was sent off for a second bookable offence and McGuinness rescued a point for the Hoops.
