The team announced Thursday it added the 76-year-old Mudd as a senior offensive assistant. The Colts also signed Klayton Adams as assistant offensive line coach.
Mudd briefly retired after 2009 only to resurface with the Philadelphia Eagles in 2011-2012 before stepping away from the NFL the past six seasons.
Mudd is back again.
Colts coach Frank Reich spent two seasons as an assistant coach with Mudd on the Indy staff in 2008 and 2009.
