The Hawks assigned Mays to the G League's College Park Skyhawks on Tuesday, Brad Rowland of PeachtreeHoops.com reports.
Mays rejoined the Hawks ahead of Monday's 113-101 win over the Thunder and played the final minute of the contest, recording no statistics. Though the G League squad won't play its next game until Sunday, Mays will join the affiliate for some extra practice time while Atlanta heads out on a two-game road trip.
