The Buffalo Bills activated veteran cornerback Leodis McKelvin. They placed wide receiver Percy Harvin on injured reserve. Harvin had a chronic hip injury. Harvin had a knee injury, too. Harvin played in five games last season, with 19 receptions for 218 yards and a touchdown. Harvin also had five carries for 31 yards and five kick returns for 108 yards. With the final two years of Harvin’s contract voidable he could become a free agent again next spring. McKelvin is coming off a broken fibula.
