Vaughn, 25, went undrafted out of UCLA in 2025. He spent time with the Indianapolis Colts during training camp last year before being waived prior to the start of the season and signing a future contract with the team after the season. He was waived again by the Colts in April.

Vaughn, who measures in at 6-foot-3 and 238 pounds, recorded eight tackles while appearing in 12 games for UCLA during his final college season. He spent the four prior seasons at Yale, which included earning first-team All-Ivy League honors in 2023. He amassed 19.5 tackles for loss, 3.5 sacks and four interceptions, including two pick-sixes, in 32 career games at Yale.

Weston went undrafted out of Florida in 2025 and was signed to Seattle’s practice squad last December following a stint with the New York Jets. He appeared in three games in 2025 – all with New York – and had two tackles while playing all 56 of his snaps on special teams.

If Weston clears waivers, he will revert to the Seahawks’ injured reserve list.
