The league wanted to use the Dome at America's Center, formerly the Edward Jones Dome, for games. But according to Kitty Ratcliffe, president of the Convention and Visitors Commission (aka Explore St. Louis), the dome didn't have dates available in February.
"We appreciate their interest in St. Louis and the Dome at America’s Center, but we just did not have the February 2019 dates available due to contracts already signed," Ratcliffe said Wednesday in a statement. "During our discussions with them last week, AAF officials indicated they were trying to identify a neutral site to host games in February but had not been successful.
