The Rapids re-signed the veteran midfielder to a multi-year contract.
"Brian has established himself as one of the top midfielders in the league, a player with an impressive track record of success, and we’re thrilled that he will continue to play an important role for our club," said Rapids Technical Director Paul Bravo. "He’s a dedicated, passionate player whose hard work and skill provides an example both for players already in our club and for youth soccer players across Colorado."
Mullan, 33, is an 11-year MLS veteran and Colorado native. He has been on five MLS Cup-winning teams, having lifted the trophy with the Los Angeles Galaxy (2002), San Jose Earthquakes (2003), Houston Dynamo (2006, 2007) and with the Rapids in 2010.
"I'm very happy to have signed a new contract with the Rapids, and excited to continue my career here in Colorado," said Mullan. "It has been great to be able to play in my home town, and I’m already looking forward to next season."
In his MLS tenure, Mullan, most comfortable as a right midfielder, has scored 27 goals and added 49 assists over 279 games.
However, in 2011, he drew considerable criticism and a 10 game suspension for a two-footed sliding tackle on Seattle's Steve Zakuani that broke Zakuani's leg and ended his season. Nonetheless, Mullan went on to make 22 appearances, scoring a goal and getting an assist over the course of the season.
