Report: Lions signing OL Trystan Colon following Frank Ragnow’s retirement

The Detroit Lions’ search for a replacement for retired All-Pro center Frank Ragnow now includes veteran Trystan Colon, according to an NFL Network report on Wednesday.
Colon, formerly known at Colon-Castillo, is signing a one-year contract, per the report. He played in all 17 games last season for the Arizona Cardinals and made a career-high seven starts at right guard.
The 27-year-old played center for the Baltimore Ravens and made four starts from 2020-22, then 11 starts at right guard for Arizona in 2023 and 2024.
He has played in 51 games and started 15. He became a free agent on March 11.
Ragnow, 29, announced in a post to social media on Monday that he is retiring after seven NFL seasons.
A first-round pick out of Arkansas and a key cog on one of the best offensive lines in the NFL, Ragnow was named second-team All-Pro last season and made the Pro Bowl four times. He started all 96 regular-season games and four postseason games he played from 2018-24 but has dealt with numerous injuries.
Tate Ratledge stepped into Ragnow’s starting role during offseason workouts. He’s a converted guard who started three seasons as a right guard for Georgia. If the Lions decide the rookie second-round pick isn’t ready, left guard Graham Glasgow has started at center and could slide to that position.
