Portland Timbers midfielder Jack Jewsbury will retire at the end of the year after playing in 14 MLS seasons.
The 35-year-old announced his plans at a club banquet on Sunday night.
"As tough as this decision was, my family and I are extremely excited about the next chapter and the new adventures ahead," Jewsbury said. "It has been an honor to represent MLS during my 14 seasons, and I feel privileged to have had the opportunity to play for two first-class organizations and fan bases that have taken this league and the sport in our country to the next level.
"I will always treasure my six years playing for Portland, including the postgame victory laps on the field with my daughters and celebrating the Timbers MLS Cup victory with the entire city."
Jewsbury ranks 10th in MLS history in regular-season games played with 348, and is one of only three players to play in 150 games with two different clubs, after Steve Ralston and Bobby Boswell.
He has played for the Timbers since they joined MLS in 2011 after spending the first half of his career with the Kansas City Wizards.
He was the Timbers' Player of the Year in 2011 and helped them win the MLS Cup in 2015.
"Jack Jewsbury has been an absolute pleasure to coach during the four years I've worked with him, and I can't say enough about him as a player, professional and person," said Timbers coach Caleb Porter. "There's no better reflection of our club and what it embodies than Jack, and his contributions on and off the pitch are immeasurable.
"He will go down at the end of the season as a legend for this club, one who put the team first and gave all he had every training session, every game. The biggest credit to his accomplished career is that, in his last season, he's playing one of his biggest roles down the stretch."
