Mankato, Minn. Former Kansas University defensive back Charles Gordon, now with the Minnesota Vikings, was carted off the field after injuring his left knee during practice on Thursday.
According to the Associated Press, Gordon, who was having a stellar camp after signing with the Vikings as a rookie free agent out of Kansas University, was injured in the afternoon session.
He appeared to be in significant pain, but Vikings coaches and trainers did not release information on the severity of the injury.
Gordon played three seasons at KU as a wide receiver, return specialist and cornerback before skipping his senior season to enter the NFL Draft.
He wasn't selected in the seven-round draft in April, but immediately signed with the Vikings. He's been competing for a cornerback and return-specialist spot on Minnesota's roster.
The Minneapolis Star Tribune said Vikings coach Brad Childress isn't scheduled to talk to the media until today, so no word on Gordon was released.
The Vikings will have a scrimmage against the Kansas City Chiefs today in Mankato.
Gordon's former teammate at Kansas, linebacker Nick Reid, is competing for a roster spot for the Chiefs.
