The Bills could be without cornerbacks Terrence McGee and Leodis McKelvin for the remainder of their spring minicamp practices. Buffalo coach Dick Jauron said on Friday that he's not sure if either will be cleared for full practice for the team's final four sessions next week. "I would say maybe," Jauron said. McGee has been out since hurting his right shoulder on May 27, while McKelvin also has been out because of an infection to his middle right finger.
