Jermaine Jones has decided to hang up his soccer boots.

The U.S. national team defensive midfielder Friday announced his retirement, ending an 18-year career in Germany and the United States and with the U.S. national team.

Jones, 36, made 69 appearances for the Americans, including performing in the 2014 World Cup. He also tallied four international goals.

He forged a reputation as a box-to-box midfielder and take-no-prisoners’ player while having a commanding presence on the field.

“After 18 years I say good bye,” Jones said on Instagram. “I have a clear vision, after I had a couple of months to concentrate on what comes next!!! THANKS to all my teammates, coaches and clubs who stuck with me & believed in me through all of the years. And a special thanks to all the fans who supported me all the way. See you all soon ✌🏽🙏🏽!!! Good luck for the game today. #🇺🇸vs🇧🇷.”

The U.S. hosts Brazil in a friendly at MetLife Stadium at 8 p.m. Friday.

In Germany, Jones performed for Eintracht Frankfurt, Bayer Leverkusen and Schalke 04.

He played for the New England Revolution, Colorado Rapids and LA Galaxy in Major League Soccer.
