Glasgow Warriors produced an excellent display to overcome Newcastle Falcons 27-17 in the Anglo-Scottish tie and qualify for the Challenge Cup quarter-finals.
The Scots controlled the majority of the match and played some free-flowing rugby to go 19-3 ahead at the break.
Johnny Matthews, Kyle Steyn and Josh McKay all touched down to give the Warriors a comfortable buffer going into the second period.
Brett Connon provided the Falcons’ sole response in the opening half before Will Montgomery touched down after the interval to put the hosts back into the contest.
However, Glasgow were much the better team and Steyn crossed the whitewash for the second time to effectively seal their passage into the last-eight, despite Joel Hodgson’s consolation score for Newcastle.
Worcester made the ideal start, touching down in the third minute via Tom Howe, but that only served to motivate the hosts.
By the end of first quarter, Lyon were 14-5 ahead thanks to Baptiste Couilloud and Romain Taofifenua tries, before they extended that buffer in the early stages of the second half through Vivien Devisme.
Ted Hill immediately responded for the visitors and Billy Searle gave the English outfit late hope, but that was extinguished when Pierre-Louis Barassi sealed the win for the Frenchmen.
Irish won 64-27 at the Brentford Community Stadium and will now travel to play either Toulon or Benetton Rugby in the last eight.
Hooker Agustin Creevy scored two first-half tries and Curtis Rona, Tom Pearson, Juan Martin Gonzalez and Kyle Rowe all touched down before the break.
Castres responded with converted second-half tries from Rory Kockott and Theo Chabouni, plus Ben Botica’s penalty, to close the gap to 40-27.
But the Exiles cut loose in the final 10 minutes as Matt Rogerson, Will Joseph, Matt Cornish and Benhard Janse van Rensburg all crossed. Paddy Jackson was successful with seven conversions.
Wasps booked their quarter-final place – a trip to either Edinburgh or Bath – with a 39-29 win at Top 14 strugglers Biarritz Olympique.
Back row Alfie Barbeary went over for a hat-trick of tries in between touch downs for Jacob Umaga and England scrum-half Dan Robson. Jimmy Gopperth landed four conversions and two penalties.
The English team were the dominant side in the first half and went into a 29-3 lead thanks to tries from Umaga, Barbeary (twice) and Robson.
Lucas Peyresblanques responded for the Frenchmen before Mathieu Hirigoyen, Steffon Armitage and Bastien Soury gave the hosts real hope.
However, Barbeary’s third try secured the win for Wasps.
