The League has confirmed that the First Division champions are set to leave their Jackman Park home for the 2013 season to take up residence at Thomond
Speaking to the Irish Times, Gavin admits discussions are in an advanced stage but the details have yet to be finalised.
"It’s not finalised but it's certainly progressing," said Gavin yesterday. "It’s looking more likely. I think it's been agreed in principle, we're just looking at the implications for the fixture list."
The First Division champions recently parted company with manager Pat Scully and want to move back to their former home at the Market Fields but substantial improvements are needed to bring it up to top-flight standards.
There is the possibility of rugby games clashing with the League of Ireland's usual Friday evening fixture slot, but Gavin doesn’t believe this will be a problem.
Thomond Park is owned by the Irish Rugby Football Union and is the home of Munster Rugby. It underwent a large scale redevelopment in 2008, bringing the capacity up to 26,500.
The Blues have previously used the venue for home games with Young Boys and Torino in European clashes in 1960 and 1971 respectively, and most recently welcomed Manchester City for a friendly during the summer.
The Shannonsiders currently play their home games at Jackman Park.
