Both had been on hand for rookie minicamp at Gillette Stadium.
Rookie minicamp visitors will be joining the 90-man roster in Foxborough.
The New England Patriots are expected to sign offensive lineman Mehki Butler and defensive lineman Isaiah Iton, according to Sunday reports from KPRC 2’s Aaron Wilson and The Draft Network’s Justin Melo.
Both free agents had been at Gillette Stadium on a tryout basis.
Butler, 24, earned NJCAA first-team All-America recognition at Iowa Western Community College in 2020 before transferring to Arkansas State. After redshirting, the 6-foot-3, 310-pound guard proceeded to start 38 games for the Red Wolves on the left side. Unselected in the 2025 NFL draft, he wore No. 63 during rookie minicamp.
Iton, 23, made stops at Northern Colorado and Hutchinson Community College before appearing in 36 games between Ole Miss and Rutgers. After logging 13 starts at defensive tackle as a senior, he signed with the Tennessee Titans as an undrafted free agent in 2024. The 6-foot-2, 294-pounder spent his rookie season on the practice squad in Nashville, overlapping with defensive line coach Clint McMillan. He was waived from his futures contract in April and wore No. 93 over the weekend.
Eight selections from the 2025 Patriots draft class officially signed their rookie contracts on Friday. Sixteen undrafted free agents additionally agreed to terms with the organization.
