After losing to Ospreys, Ulster bounced back by defeating Cheetahs, while Glasgow Warriors beat Dragons to move into third in Conference A.
Ulster and Glasgow Warriors both claimed victories on Saturday to keep themselves in pole position for a place in the Pro14 play-off quarter-finals.
Second in Conference A, Ulster bounced back from an away defeat at Ospreys last time out as they ran out 20-10 winners over Cheetahs.
Tries from Tom O'Toole and Robert Baloucoune proved enough for Ulster to claim their eighth win of the season and maintain their unbeaten run at home in all competitions this campaign.
Clayton Blommetjies drove over for Cheetahs with 15 minutes remaining, but the visitors did not have enough to set up a grandstand finish.

Glasgow, meanwhile, moved up to third in Conference A with a 30-19 comeback victory over Dragons, who took the lead through a Rhodri Williams try in the first minute.
The Warriors swiftly hit back via Tim Swinson and Grant Stewart to take a 10-point lead into the break.
Williams got his second for Dragons while Stewart doubled his tally for the home side and Huw Jones secured the bonus point after being dropped by Scotland head coach Gregor Townsend.
Ashton Hewitt's try brought Dragons back into contention but Mesu Dolokoto's late score made sure of a third straight win for Glasgow.
