The Aviva Stadium in Dublin could host the two Heineken Champions Cup semi-finals with Munster, Leinster and Ulster all involved in quarter-finals.

It would, however, take an unlikely series of results from the other ties to bring the matches to the Dublin 4 venue.

Should Saracens, the top-ranked side in the competition, beat Glasgow Warriors at the Allianz Arena on 30 March, their semi-final would be played at the Ricoh Arena in Coventry against either Munster or Edinburgh.

But if the Warriors were to cause an upset against Mark McCall's team, who beat them twice in the pool stages, then they would come to Dublin, provided that Munster overcame Edinburgh on the same day in Murrayfield.

Should the two Scottish teams win their quarter-finals, they would meet in Murrayfield for a semi-final.

Champions Leinster or quarter-final opponents Ulster would play the other semi-final in Lansdowne Road if Toulouse can beat Racing 92 in Paris.

Should Simon Zebo and Donnacha Ryan's team prevail, Leinster or Ulster, champions in 1999, would have to face the Top 14 outfit in their home ground, the Paris La Défense Arena

The semi-finals will take place on 19/20/21 April.

Meanwhile, Saracens flanker Michael Rhodes will miss that clash against Glasgow after being suspended.

Rhodes received a three-week ban following a citing for dangerous play in a ruck or maul during his side's Gallagher Premiership defeat at Bath last Friday.

He was reported for making contact with Bath lock Levi Douglas' head during the first half.

Rhodes appeared before an independent disciplinary panel, when he accepted the charge. He cannot play again until 2 April.
