Colts place DT Arthur Jones on injured reserve, ending his season

INDIANAPOLIS -- Indianapolis Colts defensive tackle Art Jones' 2015 season is officially over as the team put him and rookie linebacker Junior Sylvestre on the injured reserve list Saturday.

Jones underwent left ankle surgery Friday after getting injured in the Aug. 29 preseason game at St. Louis.

The Colts signed Jones to a five-year, $33 million contract in 2014 in an attempt for him to be their run-stopper. Jones, instead, has played only nine games with the franchise because a right ankle injury cost him seven games last season.

Sylvestre injured his ankle in Thursday's preseason finale against Cincinnati.
