Dallas Cowboys leading tackler Sean Lee has been placed on injured reserve and will miss the rest of the season because of a right big toe injury.
Coach Jason Garrett said Wednesday that Lee will have surgery in the ''next week or so.'' Garrett says an MRI showed ligament damage that will require the surgery and end hopes of Lee possibly being able to return in four to six weeks.
Lee, a third-year pro, also calls the defensive signals for the Cowboys. The Cowboys signed veteran linebacker Ernie Sims, who played 13 games last year for Indianapolis.
Dallas also put punter Chris Jones on injured reserve. The Cowboys host the Giants this Sunday.
