The Chiefs announced the signings of four free agents, including quarterback E.J. Manuel.
They also signed receivers Sammie Coates and Davon Grayson and defensive back Dontae Johnson.

Coates is a former third-round pick of the Steelers. He played 12 games with the Texans last season before they cut him Dec. 19.
Johnson is a former fourth-round pick of the 49ers. He played one game for the Bills last season after appearing in 63 games with San Francisco over four seasons.
