Bleyendaal doubt for Europe
Munster just about held onto their Top-2 status in the PRO12 when edging out a fired-up Glasgow 10-7 at Irish Independent Park.
Used as a barometer against how Saracens completely destroyed the Warriors the week before in the Champions Cup quarter-final, Munster will have to be at the peak of their powers on Saturday week at the Aviva Stadium.
Even then, there are no guarantees about making their fifth European Cup final as they look to move alongside Leinster's three triumphs.
There was an intensity to Munster-Glasgow that was right up there.
Tyler Bleyendaal was part of the collateral damage in taking a blow to the head from which he did not return, making him a doubt for the semi-final.
This comes about as second-choice Ian Keatley is battling to return from a knee injury.
The move of Rory Scannell into the driving seat at out-half only served to show how pivotal the New Zealander is as Munster became utterly predictable, Scannell resorting to lofting high cross-field balls which were returned with interest by Tommy Seymour.
While Rassie Erasmus's men dominated possession and territory for sustained spells, they could not put Glasgow away and became increasingly vulnerable once Stuart Hogg's individual brilliance reduced the deficit to three points.
The favour from Leinster means Munster are now seven points clear of third-placed Ospreys with Ulster in fourth ahead of the last three rounds.
