MLS veteran Conor Casey, a former United States international forward, announced his retirement on Thursday.

Casey completed his final season with Columbus Crew SC on Sunday before revealing he was ending his career at age 35.

"I feel very fortunate today. I've been able to make a life from doing what I love," Casey said in a statement. "This beautiful game has brought me all over the world, shown me places and people I would have never seen. From empty training fields to packed stadiums with screaming fans, it has given me back everything I've poured into many times over."

"Thank you to my family for giving me every opportunity to follow my dreams, to my friends for their support, to my wife and baby for their love, to my teammates for inspiration and to the fans for that feeling that can't be matched. Til next time."

Casey made 19 appearances for the U.S., scoring both of his goals in a 3-2 win at Honduras that secured the Americans' place at the 2010 World Cup.

Beginning his career with Borussia Dortmund, Casey spent six years in the Bundesliga with four clubs before moving to MLS with Toronto FC in 2007.

In 2007, Casey was traded to his hometown Colorado Rapids, with whom he found his greatest success, scoring 40 goals in 119 regular season games and claiming the 2010 MLS Cup.

He then scored 21 goals over three years with the Philadelphia Union before concluding his career in Columbus in 2016.
