The Milwaukee Bucks waived Ayon last week before his $1.5 million salary became guaranteed. The Hawks will pick up the 6-foot-10 Mexican's salary, which now becomes guaranteed.
The Hawks and Bucks have been involved in a series of transactions involving each other this summer. The Bucks signed Hawks' restricted free agent point guard Jeff Teague to an $8 million per season offer sheet, which the Hawks matched. The Bucks also signed Hawks backup center Zaza Pachulia to a three-year, $15 million deal earlier this month.
Ayon, who averaged 3.7 points and 4.9 rebounds in 55 games with the Bucks and Orlando Magic last season, will essentially replace Pachulia.
In February, the Bucks and Hawks had extensive trade talks involving Josh Smith but ended up not making a deal.
