Connacht's Pro 12 title hopes have been rocked by a double set-back.

The influential duo of Bundee Aki and Denis Buckley are both struggling to be fit for the rest of the season.

Buckley appears unlikely to be available again for the province this campaign after he fractured an ankle in training.

Aki, who has been one of Connacht's standout players this season, is also set to miss this weekend's game against Treviso with a knee injury, which could keep him out for longer than that.
