James Daniels: A second-round pick by the Chicago Bears in 2018, Daniels has actually spent most of his NFL career at guard despite playing center in college at Iowa. He's only played in five games over the past two seasons, though, as he suffered a torn Achilles in 2024 and a season-ending pectoral injury in Week 1 of last season. After signing Daniels to a three-year, $24 million contract in 2025, the Dolphins released Daniels in February.

Graham Glasgow: Glasgow, a 10-year veteran who's played seven with the Detroit Lions and three with the Denver Broncos, has also spent most of his professional career at guard. But after Frank Ragnow retired in June 2025, Glasgow assumed the Lions' starting center role and started 14 games that fall. He was released in March.

Ryan Bates: Bates has only been a regular starter in one of his seven NFL seasons since being signed as an undrafted free agent by the Buffalo Bills in 2019, which came in 2022. He was most recently with the Chicago Bears and now Ravens Offensive Coordinator Declan Doyle, where Bates appeared in 16 regular-season games and two playoff games last season.

Daniel Brunskill: Brunskill, who has 71 career starts across stints with the San Francisco 49ers, Tennessee Titans, and Miami Dolphins, hasn't appeared in a regular-season game since 2025. He signed with the Washington Commanders on Aug. 8, but he was waived on Aug. 30.

Nick Harris: Harris' last regular-season appearance came in 2024 when he was with the Cleveland Browns. A fifth-round pick by the Browns in 2020, Harris has six career starts.
