Leinster v Lions: Five takeaways as ‘late three-try collapse’ tames visitors and ‘unheralded sub’ wins player of the match
Following Leinster’s hard-fought 31-7 win over the Lions in their United Rugby Championship (URC) clash at Aviva Stadium on Saturday, Planet Rugby picks out five takeaways from the spicy action.
Top line
Having last weekend booked their latest appearance in the Champions Cup final, it was back to the United Rugby Championship title defence for Leinster in Dublin and they eventually didn’t disappoint, sealing victory with a late flourish against a stubbornly defiant opposition who were also challenging for a home quarter-final.
With the sun shining, Leinster revelled in a fortuitous start. Jimmy O’Brien’s offload came off Jamie Osborne’s knee but that deflection flat-footed the Lions’ defence and another hack on left the centre touching down for the opening score just over 100 seconds in.
Missed chances then became a thing, with offside scrubbing out tries for both teams while the Lions also missed a penalty before the drought ended in the 25th minute with Thomas Clarkson grabbing the converted try for a 14-0 home team lead.
The Lions, though, didn’t lose heart and after a hat-trick of sloppy kicks out on the full from Leinster, the South Africans got on the board when some flaky tackles followed and skipper Francke Horn grabbed the 35th minute converted score that left the gap at 14-7 heading to the interval.
It was a pent-up home side that re-emerged from the sheds for the second half but early pressure counted for nought, offering the Lions further encouragement and a cracking contest now developed.
The boiling point arrived on the hour with the Lions kicking a penalty to the corner, but this premium chance was lost with a Leinster intercept from Diarmuid Mangan numerous phases later.
That was crucial as the defending champions, who withdrew the struggling Sam Prendergast and shifted Ciaran Frawley from full-back to out-half, struck for the decisive 70th-minute score when Rieko Ioane ushered in Hugo Keenan.
Ioane himself then accounted for the bonus point score four minutes later and O’Brien added the fifth try in the final minute, confirming a Leinster win that gives them hope of a second-place finish with one round remaining.

Lions wounded by admirable adversity fight
Arriving in Dublin on the back of a six-game winning run, the Lions had it all to do to show that they could be equally as effective away from home as they had been in using the advantage of their at-altitude base in Johannesburg to propel them up the URC ladder.
Not since a January 23 draw at the Ospreys in Wales had they played away from Ellis Park and they endured a horrible start in Dublin, going behind less than two minutes in and then having Ruan Venter, one of their most impressive players in 2026, taken away on a medical cart after he was woundingly chop tackled on the knee after he had just knocked on.
The knocks to their confidence kept on coming, with Chris Smith missing a 17th-minute penalty kick from distance and then Siba Mahashe frustratingly seeing a try disallowed a few minutes later after Erich Cronje was deemed to be offside when playing the nine.
The momentum killers continued with a Morné van den Berg pass getting intercepted, but they were clearly learning much in this period of adversity as they struck for a try before half-time and their gritty defence was evident in the opening spell of the second half which included holding Leinster up over the try line.
However, when it came to having their attack light it up and get the converted try that would have levelled the contest, they were found wanting. Despite getting some joy at the scrum, their maul didn’t gain the necessary vital traction on the hour near the Leinster line and it hurt.
The chance – and a whole pile of territory – was lost with another Van den Berg pass getting intercepted, and that was the spark for the late three-try collapse that now has the home quarter-final they want in jeopardy. The wounded Lions have it all to do next weekend at Munster.

Another clunky Prendergast effort
The more Prendergast plays this season, the more he unfortunately becomes an accident waiting to happen. Having done terribly in defence when brought on as a sub against Toulon last weekend, he was given a start at 10 in this URC match and did nothing to suggest he can dislodge the jersey from Harry Byrne for the May 23 Champions Cup final.
If anything, what he produced, and then what Frawley brought to the party when he moved into out-half, could well have damaged his chances of even holding onto the place on the bench he had against the French.
His kicking versus the Lions left much to be desired. For example, he was lucky to find touch with an 11th-minute penalty after it was set to be kept in play until a poor attempted catch. A kick out on the full then contributed to the momentum the visitors were generating, a development not helped by him faking an injury football style.
That led to an all-in bust-up and it was telling that when tempers cooled, that Prendergast was admonished by referee Hollie Davidson for his reaction to PJ Botha trying to block his clearance.
It was when a penalty was kicked dead from the 10-metre line with the score still at 14-7 that the plug was pulled with 16 minutes remaining and he was subbed off. By the way, there was no great uptick in his level of tackling either and having been used as a speed bump by Mahashe, he would have been relieved the 21st-minute try was chalked off.
Frawley’s kicking wasn’t supreme – he too was a kicking out on the full culprit in that nervy late first half period – but he got through a pile of useful handling and running work when shunted into 10 with Prendergast off. It was the type of cameo that can earn him a bench spot in Bilbao.
Sub wins player of the match award
What ultimately did for the Lions was the strength of the Leinster bench, and its introduction brought the best out of their All Black starter Ioane. The well-remunerated back has started to fire up in recent weeks after a winter period where the form expected from a marquee signing like him was underwhelming.
He is now picking menacing lines of running, and he was rewarded here with a well-taken 74th minute try four minutes after he had blasted through the South African defence to lay it on a plate for Keenan to score the try that gave Leinster a two-score lead after the match has been stuck at 14-7 for what seemed like an eternity.
Whereas the Lions got weaker the more they went to their bench, Leinster’s strength only increased every time they made a sub, given the calibre of stars they had in reserve.
Dan Sheehan, Andrew Porter and Keenan all helped to ensure the final part of this match was decisively played out to the tune of a 17-0 score in favour of the home side. However, this was an evening when unheralded replacement Mangan produced such an impactful display that he was voted player of the match.
The second row was a first-half introduction, and he played up a storm. It was fitting that the key moment, his interception of Van den Berg, was so crucial to the game’s outcome. He is definitely a new name to watch out for.

What the result means for the play-offs
This was massive win for Leinster with regard to the end of season play-offs. With the second-place Stormers held to a draw at Ulster on Friday night, the door was ajar for Leo Cullen’s side to close the gap on the Cape Town franchise provided they took care of their South African opposition.
With the Lions hunting a top four finish, it led to a tension-filled encounter in Dublin before Leinster ran away with it in the closing minutes. The victory still has them in third spot on the table, but they are now only one point behind the second place Stormers and two adrift of the table topping Glasgow.
That gives the champions a shot at moving up the table in next weekend’s final round if they beat Ospreys in Dublin and Glasgow (at Ulster) or Stormers (at Cardiff) slip up. The Lions, meanwhile, have dropped out of the top four, heightening the importance of their final round visit next Saturday to Munster.
