Glasgow and Lyon will face each other in the last eight after 27-17 and 31-17 victories over Newcastle and Worcester.
Early tries from Johnny Matthews and Kyle Steyn set Glasgow on their way at Newcastle and further try either side of half-time through Josh McKay, and Steyn again kept them in control. Newcastle hit back in the second period, scoring converted tries through Will Montgomery and Joel Hodgson, but they could not make further inroads on the deficit.
Tom Howe, Ted Hill, and Billy Searle went over for Worcester. Still, it was not enough for Lyon, who led 14-5 at the interval after tries from Baptiste Couilloud and Romain Taofifenua. Vivien Devisme’s converted touchdown put Lyon 21-5 ahead, and after Hill’s try reduced the gap to 21-10, the French side ensured victory through Ethan Dumortier’s late converted try.
