The Indianapolis Colts put Tyler Varga on the reserve-did not report list Tuesday.
Varga, a Yale grad, played in three games in 2015, but finished the season on injured reserve with a concussion. He participated in the Colts' offseason workouts.
Coach Chuck Pagano did not take questions when the Colts reported to training camp at Anderson University. Indy has its first practice Wednesday.
Indy also signed veteran tight end Chase Coffman and waived cornerback Daniel Davie.
Coffman played in 37 games with Seattle, Tennessee, Atlanta and Cincinnati.
Indy also put defensive end Henry Anderson and tight end Darion Griswold on the physically unable to perform list. Safety Clayton Geathers and tight end Mike Miller wound up on the non-football injury list.
