McCutcheon played at USC from 1995 to 1998 and was selected by the Cleveland Browns in the third round of the 1999 draft.
He was an NFL starter for seven seasons, and Bowles was his position coach with the Browns from 2001 to 2004.
McCutcheon worked for the Jets as a training camp intern in 2013 and last season for the Arizona Cardinals, for whom Bowles served as defensive coordinator.
McCutcheon is the son of former Los Angeles Rams running back Lawrence McCutcheon. He is also the uncle of USC tailback Tre Madden.
