In December 2005, Firhill became the home of Glasgow's professional rugby union team, Glasgow Warriors, when they moved from their previous base at Hughenden Stadium. After returning to Hughenden in 2006, the Warriors took up a two-year residency at Firhill from the start of the 2007–08 Celtic League season. This was extended in April 2009 for a further five years. Glasgow Warriors left Firhill after the 2011–12 season and moved to Scotstoun Stadium.
