The Chiefs are putting wide receiver Marquise Brown on injured reserve because of the dislocated shoulder joint he sustained in the preseason.

Las Vegas got a pair of defensive touchdowns for the second straight week, and the resurgent Raiders held off the sloppy Kansas City Chiefs 20-14 on Monday to keep their postseason hopes alive.

Patrick Mahomes saw his first extended action of the preseason, throwing for 105 yards and a touchdown, and the Kansas City Chiefs beat the Arizona Cardinals 38-10 on Saturday night in the second preseason game for both teams.

The Kansas City Chiefs allowed wide receivers JuJu Smith-Schuster and Mecole Hardman to walk away in free agency, and in their place they signed a couple of relative unknowns while taking a gamble on an injury-prone talent and unproven draft pick.

It’s sometimes hard to believe that Kansas City Chiefs quarterback Patrick Mahomes, for all that he’s accomplished during his young but brilliant NFL career, would carry such a considerable chip on his shoulder.
