Connacht have confirmed that second-row Michael Swift fractured his leg during last week's game between the Eagles and the Ulster Ravens.
The 37-year-old is now facing six to eight weeks on the sidelines.
However, there is better news for the province as Jake Heenan, Mick Kearney and Tiernan O'Halloran are all available for this week's Pro 12 clash with the Scarlets.
