The Jets can't announce the nature of the injuries for liability reasons.
McGill, a 6-3, 290-pound product of the University of Georgia, recently completed his first season with the Cologne Centurions of NFL Europe. He originally entered the NFL as a rookie free agent with the Indianapolis Colts in 2002 and spent the season on their injured reserve list. He was waived by the Colts on February 26, 2003.
McGill was signed because of the Jets unstable backup center situation.
