Full-back and captain Gavin Duffy explained: "We are calling on all the people of Connacht to come out and support our team.
"Tickets for the match will be hard to come by but there are many ways you can support the team mainly through our Facebook page (www.Facebook.com/ConnachtRugby) where you can now upload a video, post a picture or simply type your message of support which will be read in by the team in the run-up to our Heineken Cup games.
"When we played Toulon in the semi-final of the Amlin Challenge Cup two seasons ago, teams and schools from across the province sent in their messages and we had them all displayed on boards around the dressing room.
"It really hammered home the support we had from all over and it was a huge motivator for the team.
"This year we face a similar challenge so we're asking people from every corner of the province to do the same and upload their messages of support to our Facebook page."
To upload your picture, video or message, log on to www.Facebook.com/ConnachtRugby. The top 100 images of support will be used to form part of Connacht Rugby's 'The Green Mile'.
