Ravens rookie Bilhal Kone carted off after gruesome knee injury.

BALTIMORE -- Ravens cornerback Bilhal Kone tore a ligament in his left knee during Thursday night's preseason-opening 24-16 win against the Indianapolis Colts and will miss the season, coach John Harbaugh said. Kone, a rookie sixth-round pick, was defending Colts wide receiver Ashton Dulin down the left sideline at the end of the first quarter when he went down in the end zone on an incomplete pass. He was visibly in pain and immediately grabbed his left leg. Ravens athletics trainers put Kone's leg in an air cast before carting him off the field. He had been competing for one of the final cornerback spots for Baltimore. Last season, Kone led Western Michigan with nine passes broken up. He added 70 tackles and one interception.
