Ospreys returned to winning ways with a 26-15 victory over Glasgow Warriors to cement their spot in the Pro12 top four.
The Welsh region are back up to second in the table, taking the position back from Munster after last week's defeat to the Irish side.
Keelan Giles' 12th try of the season and a score from Josh Matavesi put Opsreys in control, but they were pegged back by Corey Flynn's try for Glasgow.
The visitors moved ahead after the break when Peter Murchie touched down as the hosts waited for an apparent high tackle on Giles to be called.
But Ospreys were not to be denied, Tyler Ardron and Kieron Fonotia tries securing a bonus-point victory, while Glasgow are left 12 points off the play-off places.
Champions Connacht ran in four tries, with Craig Ronaldson contributing 17 points, as they saw off Treviso 34-19, while Ulster closed on the top four with a 40-17 bonus-point win over rock-bottom Zebre.
