INDIANAPOLIS — The Indianapolis Colts will be without three key members of their defense Sunday when the Arizona Cardinals come to Indianapolis for the 2017 home opener at Lucas Oil Stadium.
Head coach Chuck Pagano said two starters, safety Darius Butler and inside linebacker Antonio Morrison, and another key backup, inside linebacker Anthony Walker, have officially been ruled out.
Walker, who suffered a hamstring injury last Sunday in the Colts’ 46-9 season-opening loss to the Los Angeles Rams, had not practiced all this week; Morrison also did not practice this week with an elbow injury.
