INDIANAPOLIS -- The Indianapolis Colts are waiting to learn the severity of defensive tackle Art Jones' left ankle injury, but there is a "very good chance" surgery will be required, according to a source with knowledge of the situation.
Jones, the Colts' most effective run-stopper, has seen multiple doctors about his ankle. How long he will be sidelined won't be determined until after surgery, if it's necessary.
The Colts could place Jones on short-term injured reserve, which would allow him to begin practicing after six weeks and play in a game after eight weeks.
The worst possible scenario is that Jones goes on season-ending injured reserve.
Jones injured his ankle in the first quarter of the team's preseason game at the St. Louis Rams on Saturday. He was wearing a walking boot and using crutches as he left the Colts' locker room Tuesday.
Jones, who signed a five-year, $33 million contract with the Colts in March 2014, also missed seven games last season with a right high ankle sprain.
