According to multiple sources, FC Dallas right back Reggie Cannon was yesterday called up to the U.S. Men's National Team Gold Cup roster.

In order to be added at this time, Cannon has to be an injury replacement for someone on the original 23-man roster. A player may be replaced on the roster up to 24 hours before a team's first match of the group phase in the case of injury, but the replacement has to have been on the 40-man preliminary roster, which Cannon was.

Update 1 - 11:30 am Tuesday: Cannon is not at FCD training today, via @ArmanKafai.

Update 2 - noon Tuesday: FCD coach Luchi Gonzalez confirms Cannon's absence is because of his call-up:

So it seems Cannon will not be available for FC Dallas for their Wednesday U.S. Open Cup match against OKC Energy.

Update 3 - 11:30 am Tuesday: Based on various reports and rumors, it looks like Cannon is replacing Tyler Adams.

Based on other rumors making the rounds, looks like @DieRotenBullen wonderkid 🇺🇸 Tyler Adams (20) is sitting this Gold Cup out.
