No, not the Arena Football League, but rather the Arizona Fall League. That's where the White Sox are sending six of their up-and-coming prospects.
In the "guys we've discussed" category, it'll be IF's Micah Johnson & Marcus Semien and pitchers Charlie Leesman & Stephen McCray, and in the "soon to be discussed" category, it's pitchers Chris Bassit & Kevin Vance. Those six guys will be a part of the Glendale Desert Dogs, a squad also made up of Dodgers, Twins, Marlins, and Reds prospects.

The Arizona Fall League is something that's often looked forward to and commonly serves as one of the final steps before a team decides whether or not to call a prospect up to the big leagues.
The AFL season runs from October 8th through November 14th of this year. I feel at least somewhat confident in saying that it'll mean someone like Marcus Semien, which the team would like to see play every day, will not be a part of the south side September call-ups.
Still, the rosters of the AFL teams can change before and during the season, so we'll likely have at least a little more news on its front before it actually starts up.
