The Union will host Swansea City A.F.C. of the English Premier League in an international friendly on July 15 at 7 p.m. at Talen Energy Stadium.
The Union has regularly played friendlies against EPL teams. They hosted Crystal Palace, playing to a 0-0 draw, on July 13 last year. Swansea is on the south coast of Wales.
The friendly is scheduled in a break between two Major League Soccer road games for the Union. They visit Sporting Kansas City on July 6 and don't resume MLS action until July 19 at Montreal.
The Union said the friendly counts as the bonus game for all full-season ticket members.
