The U.S. men’s national team won’t be playing World Cup quarterfinalist Colombia in a friendly on Sept. 9 after all. After a verbal deal had been reached between the two countries to stage the game in San Antonio’s Alamodome, Colombia did not sign the contract by Monday’s deadline, two sources familiar with the deal told SI.com.

The U.S. is now unlikely to play a friendly on that date, which falls in FIFA's September international fixture window. U.S. Soccer has already announced a friendly against the Czech Republic six days earlier in Prague on Sept. 3. There are other windows from Oct. 6-14 and Nov. 10-18 to round out the year. As of now, the USA has a scheduled friendly against the Republic of Ireland set for Nov. 18 in Dublin.

Colombia is dealing with uncertainty regarding its coaching situation. José Pekerman, the Argentine who led Colombia in Brazil, is in contract talks with the Colombian soccer federation.

Not getting to play Colombia is a missed opportunity for the U.S., which would have faced a stern test against a Colombia team that could have included a host of players who excelled at the World Cup like Golden Boot winner James Rodríguez and Juan Cuadrado. Radamel Falcao, who has recovered from the torn ACL that robbed him of a World Cup appearance, also could have posed a challenge for the U.S. defense.

Colombia has already announced a friendly against Brazil – a rematch of the World Cup quarterfinal in which Neymar suffered a fractured vertebrae – on Sept. 5 in Miami.
