Connacht will be without hooker Sean Henry for the rest of the RaboDirect PRO12 season after it was confirmed that he will undergo neck surgery.
The 26-year-old is expected to miss the season run-in as the team hopes he will be fit to return during pre-season training in Galway in June.
In other news from the Sportsground, scrum-half Paul O'Donohoe is unavailable this week after suffering a back injury during last weekend's warm-up for their away fixture with Zebre.
"Nathan White and Eoin McKeon are now both available for selection as the province aim for their third league win on the trot," added a statement.
"Robbie Henshaw will continue to train with the Ireland squad, but will return to his province ahead of the (Treviso) game on Saturday."
