Kansas City Chiefs WR Marquise Brown exits in first quarter

Wide receiver Marquise Brown left the Kansas City Chiefs ' preseason game against the host Jacksonville Jaguars in the first quarter with a shoulder injury on Saturday at EverBank Stadium.

The Chiefs said Brown has a shoulder injury and was questionable to return to the game, but Kansas City put its backups in during the second series of the game, making it unlikely he would play again.

Brown caught a pass on the first play from Patrick Mahomes for an 11-yard gain but immediately after headed to the sideline to be examined by medical personnel.

Brown was one of the Chiefs' biggest free agent additions during the offseason. The Chiefs are expecting Brown and first-round draft pick Xavier Worthy to improve their wide receiving play, a disappointment last season.

Last season, with the Arizona Cardinals , Brown had 51 catches for 574 yards and four touchdowns.
