Vikings Sign Bills OT Ryan Van Demark To Offer Sheet

The Vikings have signed Bills restricted free agent offensive tackle Ryan Van Demark to an offer sheet, according to Ian Rapoport and Tom Pelissero of NFL Network. Buffalo has five days to match, but the team will not receive compensation if it allows Van Demark to leave.

The Bills gave Van Demark, an undrafted free agent, an original-round tender worth $3.52MM. The Vikings offered Van Demark a one-year, fully guaranteed deal worth $4.2MM, Aaron Wilson of KPRC 2 reports.

After starting 43 games at UConn, Van Demark signed with the Colts in 2022. The 6-foot-6, 307-pound was part of their final roster cuts that year, but he caught on with the Bills’ practice squad.

Although Van Demark did not appear in any games as a rookie, he played 43 and started six from 2023-25. He combined for 511 offensive snaps over the past two seasons. During his first career 17-game campaign in 2025, Van Demark logged 154 snaps at right tackle and 43 at left tackle.

With Dion Dawkins and Spencer Brown entrenched as the Bills’ starting bookends, Van Demark will continue to fill a swing tackle role if they match the Vikings’ offer sheet. In the event the cap-strapped Bills deem it too pricey, Tylan Grable and Chase Lundt are among in-house options who could take over for Van Demark.

Like the Bills, the Vikings have a pair of established and expensive tackles in Christian Darrisaw and Brian O’Neill. But injuries have been a problem for Darrisaw, who has never played in more than 15 games in any of his five seasons. The 26-year-old tore his ACL and MCL in 2024, limiting him to seven games then, and his recovery dragged into ’25.

Darrisaw played just 10 games last year, and with the Vikings managing his workload, they put him on season-ending IR in late December. O’Neill posted perfect attendance during his second Pro Bowl campaign in 2024, but he sandwiched two 14-game seasons between it. Adding Van Demark would give the Vikings some insurance behind Darrisaw and O’Neill in 2026.
