Castres hoping for turnaround at home
Munster launch their Champions Cup campaign on Sunday against Castres at Stade Pierre Fabre, but the Top 14 side will hope that home comforts bring some solace after their shock 27-22 defeat to Brive last weekend.
Julien Dumora gave Castres an early lead and he added another try in the second half, but a sloppy second quarter cost Castres, who were unable to close the gap sufficiently.
Dumora and Julien Caminati had their tries converted late on, but the yellow card for lock Victor Moreaux proved costly for Munster's next opponents.
It will be a six-day turnaround for Munster as they then prepare to take on Racing 92 at Thomond Park, but the Parisian outfit will aim for victory over Leicester Tigers in the meantime.
Racing enter this game on the back of three defeats in a row following their latest 16-9 loss at La Rochelle.
Three Maxime Machenaud penalties was their sole return as Vincent Rattez's first-half try and the boot of Alexi Bales kicked La Rochelle to the win.
Tigers are now in sixth place in the English Premiership after they recorded the narrowest of wins, 28-27, away to London Irish.
Tigers seemed to be cruising to the win after Nick Malouf, Will Evans and Jonny May crossed, but two late converted tries from David Paice and Alex Lewington almost saw they pipped at the finishing line. A win in Paris would set up their Champions Cup drive.
