Former Sporting Kansas City defender and captain, and Kansas City native, Matt Besler has called time on his professional soccer career. Besler announced his retirement in a post on Twitter today after Austin FC’s inaugural season ended on Sunday. Besler hadn’t played for Austin since suffering a concussion in a 2-1 loss to the Vancouver Whitecaps on September 4th. He made 20 appearances for Austin this year at center back, including appearing in both games in Kansas City when Austin came to visit. The 34 year old made 314 appearances in league play, 294 of them for Kansas City and 285 starts.
