Brian Carroll’s career has become synonymous with longevity in MLS. Thursday, the Union legend called time on that career.

The 36-year-old midfield announced his retirement Thursday, after 15 pro seasons that saw the slight but cerebral midfielder assemble a resume surpassed by few in MLS history.

Carroll has been with the Union since 2011, the longest tenured member of the club. He ranks second in club history in games played (165) and first in both starts (156) and minutes (13,819). Carroll hasn’t played this season, the first time he’s been limited to fewer than 21 games in a season since his rookie campaign, when he didn’t see the field with D.C. United.

In 15 seasons with the Union, D.C. and Columbus, Carroll is tied for fourth in games played in MLS history among field players at 370 (he can be passed by Seattle’s Chad Marshall Sunday). Carroll is sixth among field players in starts with 345, one behind Toronto’s Drew Moor. Add in goalies, and Carroll is tied for sixth in games and eighth in starts.

He’s also sixth among MLS players in all-time minutes played at 30,776. Staggeringly, Carroll has never been red carded in his MLS career despite playing so frequently in a combative position in the center of the park. He holds the honor of the most career minutes in MLS without a red card. (Second is Landon Donovan at 28,898, but the long-time Galaxy forward has 119 yellow cards to Carroll’s comparatively paltry 57.)

Carroll has nine MLS goals to his name to go with 17 assists. In seven Union seasons, Carroll scored five times (including a career-high two goals in 2013) to go with three assists.

Carroll made the playoffs nine straight seasons from 2003-2011, the latter with the Union, then contributed 23 starts to the Union’s 2016 playoff berth. Carroll started 20 career MLS playoff games, winning MLS Cup in 2004 with D.C. (and assisting on Alecko Eskandarian’s opening goal in the final) and in 2008 with the Crew. Carroll lifted the Supporters’ Shield four straight years from 2006-09.

Carroll, a second-round draft pick (11th overall) of D.C. in the 2003 SuperDraft out of Wake Forest, was capped eight times by the U.S. national team from 2005-10.

Carroll and two of his brothers – Jeff and Pat – played in MLS, the only set of three brothers to play in MLS, per the league’s Facts and Record Book. Brian and Jeff were teammates for two seasons in D.C.

Carroll was capped eight times by the U.S. from 2005-10. He won MLS Cup in 2004 with D.C. United and 2008 with Columbus and was a four-time winner of the Supporters Shield from 2006-09.
