The Kansas City Chiefs placed wide receiver Mecole Hardman on injured reserve Saturday with a knee injury.Chiefs head coach Andy Reid told reporters Friday that Hardman suffered the injury before the team’s on-field work when his “knee locked up on him.”The earliest Hardman can return is Week 18 against the host Denver Broncos.Hardman, 26, signed a one-year deal with the Chiefs in June, just months after he caught the game-winning touchdown in Kansas City’s 25-22 overtime victory against the San Francisco 49ers in Super Bowl LVIII.A three-time Super Bowl champion, Hardman has 12 catches for 90 yards as well as five rushes for 62 yards and a touchdown this season. He also has 20 punt returns and five kick returns.
