Thurman Thomas plans to retire and will sign a one-day contract with Buffalo so he can leave the NFL as a Bill, his agent said Tuesday.
Thomas suffered a serious knee injury in November and does not intend to resume his career with the Miami Dolphins. He will be released by the Dolphins some time after Feb. 22, according to his agent, Leigh Steinberg.
Thomas, the Bills' all-time leading rusher, will end his career ninth on the NFL's all-time rushing list with 12,074 yards. All but 136 of those came with the Bills, who picked him in the second round of the 1988 draft.
Thomas stands sixth on the NFL's all-time total yards from scrimmage list with 16,532 yards, and he has the seventh-most 100-yard rushing games (46).
His final season ended after nine games with Miami when he tore the anterior cruciate ligament in his right knee.
