Big 12: Charles Branson
Posted by ESPN.com's Tim Griffin
Briscoe, a playmaking receiver who led the Jayhawks in receiving yardage and touchdown receptions last season, missed all of spring practice after an undisclosed violation of team rules.
Crawford, a former national junior-college rushing leader, was suspended midway through the spring and kept out of the Jayhawks' spring game on April 11 for another undisclosed violation of team rules.
"I've no comment on any issues that I'm dealing with in-house," Mangino said.
The Kansas City Star reported that Crawford was arrested and then unarrested early on the morning of April 5. It was the same time that Kansas redshirt freshman offensive lineman Ben Lueken sustained head injuries after an incident at the Jayhawker Towers student dormitory.
Lueken either was hit by or rolled off of a moving vehicle. He was hospitalized for several days before he was released.
Mangino said he visited with Lueken on Monday.
"Ben is doing well, Ben is feeling good," Mangino said. "He looks great."
The Star reported Tuesday that the case involving Lueken is currently in the hands of the Douglas County District Attorney's office, where district attorney Charles Branson will decide whether to charge the driver of the vehicle.
The departure of both suspended players could have drastic effects on whether the Jayhawks are able to contend for their first Big 12 title game appearance in 2009.
