In 1953, the Lions won their second consecutive NFL championship, though Box's receiving statistics declined significantly with only 16 receptions for 403 yards. He was reportedly "robbed of his blinding speed by a leg injury," though he did manage a career-long 97-yard touchdown reception against the Green Bay Packers on Thanksgiving Day 1953 which would remain a Lions record until 1998. In the 1953 NFL Championship Game, he had four receptions for 54 yards.
