Bates was waived by Chicago on Tuesday.
Bates was signed as an undrafted free agent in May, yet he was unable to make the 53-man roster in Chicago. Though he wasn't able to secure a roster spot behind fellow tight ends Cole Kmet, Gerald Everett and Marcedes Lewis, the 24-year-old's prowess as a blocker could help him to catch on with a practice squad around the league.
