Mason was waived by the Seahawks on Thursday, John Boyle of the team's official website reports.
Mason signed with Seattle as an undrafted free agent May 1, but he will now be placed on waivers. The tight completed his collegiate career with a senior campaign with Wisconsin in 2025, reeling in 30 of 53 targets for 398 yards and four touchdowns. If Mason goes unclaimed on waivers, there's a chance that he sticks around with the Seahawks as a member of the team's practice squad.
