Two more MLS teams dropped out of the U.S. Open Cup against lower-league competition in Round of 16 action Wednesday.

Defending champion Sporting Kansas City lost at home, 1-0, to USL PRO affiliate Orlando City, which wasn’t even playing its on-loan MLS players. Chivas USA lost in overtime, 3-1, to the NASL’s Carolina RailHawks on the road.

From a U.S. Soccer news release: “As the only Division II and III sides to reach the quarterfinal round, the RailHawks and Orlando City have each earned the $15,000 prize money as the teams advancing the furthest in the competition from their respective divisions.”

The Des Moines Menace (PDL) also won a $15,000 bonus awarded to an amateur team that advances furthest, but that came by way of a tiebreaker over FC Tucson, Ocean City Nor’easters and Reading United AC for beating an opponent in a higher league.

One game was postponed to Thursday afternoon, Chicago vs. Columbus, due to inclement weather (this post will be updated upon completion of that game).
