Havili has been placed on the regular season PUP list with an undisclosed injury, ESPN reports. Havili did not practice during the preseason and it's not clear when he'll be able to return. He'll miss at least the first six weeks due to the PUP designation. Mario Harvey will begin the season as Indy's only fullback, although he may not play the position much since the Colts frequently use tight end Dwayne Allen in the fullback role.
