Mack (undisclosed) was waived/injured by the Packers on Tuesday, Doug Kyed of Pro Football Focus reports.
Mack was signed to a reserve/future deal in February, but he ultimately failed to secure a spot on the Packers' roster for the 2022 campaign. The tight is dealing with an undisclosed injury, and assuming he passes through waivers unclaimed, he'll revert to injured reserve.
