Munster's Anthony Foley and Neil Doak from Ulster have been named as the coaching ticket for the O2 Ireland Wolfhounds who take on the England Saxons at Kingsholm on Saturday, January 25, 2014.
Swift explained: "I was told by the doctors that I had two tears on my kidney and that the earliest I'd be back playing is eight weeks time, so there's a possibility I might not play again this season.
"I'm very disappointed as the season was going very well for me and I'd played in every game since we played South Africa in August.
"The important thing now is to focus on recovering and getting back to training but for now I've been told to get plenty of rest."
The London-born forward, who started off life in the back row, has played in all of Connacht's 18 competitive games this season and has made a total of 131 appearances for the westerners to date.
