[2] Connacht's participation in European rugby's most prestigious club competition, the Heineken Cup, for the first time in the 2011–12 season spurred a new phase of development at the Sportsground to extend formal capacity to 7,500 supporters.

[6] This series of improvements came on the back of developments which the IRFU had helped to fund in the preceding years, such as a new playing surface, a new clubhouse and floodlighting, while a new gymnasium had been built in 2008.

Following a delay due to the COVID-19 pandemic, Phase 1 of the redevelopment began after the 2021/22 season with the installation of a new 3G pitch and LED floodlights.

In 2023, Connacht Rugby Stadium Limited entered into a new lease with Greyhound Racing Ireland.

Connacht Rugby Stadium Limited acquired the exclusive naming rights to the property.

Construction on the new North Stand is due to begin after the 2023/24 season, which will involve the demolition of existing Clan Terrace and Clubhouse.
