Connacht extended their lead at the top of the Pro12 table after a superb away performance in a 28-23 win over Edinburgh.
The break in the Six Nations allowed the return of Nathan White and Quinn Roux to the Connacht lineup, and by half-time the visitors were 14-0 up at Murrayfield, courtesy of tries by Alan MacGinty and Jake Heenan.
Further scores by Bundee Aki and Eoin McKeon ensured that Edinburgh's spirited second-half fightback didn't derail Pat Lam's side, who now sit six points clear at the top of the table.
Fourth-place Ulster bounced back from a disappointing run of form with a near-flawless game as they cruised to a 32-0 victory over struggling Zebre.
Fly-half Paddy Jackson kicked three conversions and three penalties, while number eight Nick Williams gave an all-star performance and scored two tries to the delight of the home crowd at Kingspan Stadium.
Bottom club Benetton Treviso gave Scarlets a scare with a resurgent second-half performance but the Welsh region clung on for a 24-15 win at Parc y Scarlets.
Treviso were a wounded animal after narrowly losing to Munster in their previous outing, and a brace of tries from Robert Barbieri helped them force Scarlets to play some of their best defensive rugby to ensure the points stayed in Wales.
