KANSAS CITY, Mo. (AP) - — Members of the Kansas City Chiefs angrily spoke out Sunday against thousands of fans who cheered when quarterback Matt Cassel left a 9-6 loss to the Baltimore Ravens with a head injury.
Cassel has been the focus of frustrated fans for the past couple years, many of them booing him when he appeared during a celebrity softball game this summer.
The angst reached a tipping point when Cassel, who committed four turnovers against Baltimore, was hammered by the Ravens' Haloti Ngata while completing a pass in the fourth quarter.
Cassel remained on his back for several minutes while fans began to cheer. He eventually got to his feet with some help and walked off the field under his own power.
"It's 100-percent sickening," Chiefs tackle Eric Winston said of the fans' reaction.
Quarterback Matt Cassel has been knocked out of the Chiefs' game against Baltimore on Sunday after getting hit by the Ravens' Haloti Ngata while attempting a pass.
Cassel remained flat on his back for several minutes before getting helped up and walking off the field under his own power. Brady Quinn started warming up and entered the game to a round of applause.
Cassel has been the subject of much angst by Chiefs fans during a 1-3 start to the season, and a banner towed by an airplane before the game implored coach Romeo Crennel to bench Cassel - and the Chiefs to fire general manager Scott Pioli.
Cassel was 9 of 15 for 92 yards and two interceptions when he left the game.
