The Bills and Brown agreed to a four-year extension Friday, Mike Garafolo of NFL Network reports.
The specifics of the 2021 third-round pick's deal have yet to be reported, but Brown is now under contract with the Bills through 2028. Brown started all 17 of Buffalo's regular-season games in 2023, and after Friday's extension, he's expected to continue anchoring the right side of the Bills' offensive line for years to come.
