INDIANAPOLIS (AP) Indianapolis Colts defensive lineman Arthur Jones has been suspended for the first four games of the 2016 season for violating the NFL's policy on performance-enhancing substances.

Jones has struggled to stay on the field since signing a five-year, $33 million contract in 2014. He missed seven games in his first season with Indy with an injured right ankle. He missed all of last season with an injured left ankle he sustained during the preseason.

Jones won't be eligible to return to the team until Oct. 3 but will be allowed to participate in training camp and preseason games.
