Defender Hannover 96 Bundesliga
Cherundolo announced his retirement from football Wednesday, citing persistent knee problems, ESPN FC reports.
Cherundolo will remain with Hannover as an assistant coach with the U-23 team. Cherundolo, who has 87 caps for the U.S. men's national team, has had multiple knee surgeries over the last two years, and simply could not continue playing as a result. He has played in three World Cups, and has spent his entire professional career playing for Hannover, the longest run for any American in the Bundesliga.
