Livings has not practiced since undergoing arthroscopic surgery on his right knee on Aug. 2, his second such operation since last season. Owner/general manager Jerry Jones has said that Livings, whose $1.7 million salary is guaranteed, has a degenerative condition in the knee.
Livings started all 16 games last season, his first with the Cowboys after signing a five-year, $18.7 million deal in free agency, but the team entered training camp looking to replace him in the starting lineup.
Ronald Leary, an undrafted second-year player who spent most of his rookie year on the practice squad, was likely to beat out Livings for the starting job at left guard regardless of health. Leary is also recovering from arthroscopic knee surgery, but the Cowboys are optimistic that he will be able to play in the Sept. 8 season opener against the New York Giants.
Putting Livings on injured reserve creates a vacancy on the Cowboys’ 53-man roster.
