Connacht have announced that they will be installing additional temporary terracing in the Sportsground for the Guinness Pro14 clash with Munster on Saturday evening.
The decision has been taken due to the high volume of ticket sales and will increase the capacity to a maximum of 8,129.
The increase in capacity in the Sportsground comes after Connacht were granted planning permission for a €30m redevelopment of the stadium on College Road.
The redevelopment will include an increase in capacity to 12,000 spectators and the development of a high performance training centre on site.
Making the announcement, Head of Commercial and Marketing at Connacht Rugby, Brian Mahony said: "Our Christmas interpro with Munster always creates a huge demand for tickets and this year has seen an unprecedented level of ticket sales.
"To meet this demand, we have increased our capacity for the game to our maximum of 8,129. The additional terracing will be installed at the Bohermore and College Road ends of the ground.
"These Christmas interpros create an incredible atmosphere and supporters are advised to purchase tickets early and arrive on time for the game on Saturday evening."
