Dallas Cowboys nose tackle Jay Ratliff and owner/general manager Jerry Jones got into a locker room confrontation on Dec. 2 in which the two had to be separated, ESPN Dallas reported Monday.
After the Cowboys' victory over the visiting Philadelphia Eagles, Jones tried to convince Ratliff to return from a groin injury. Ratliff yelled back at Jones and teammates intervened. Ratliff then finished dressing and angrily left the locker room.
Ratliff's agent, Mark Slough, would not comment.
Ratliff did not play in Sunday's 20-19 win at the Cincinnati Bengals, staying in Dallas. He cut last Wednesday's practice short because he was still bothered by the injury.
Ratliff, a four-time Pro Bowler, has 25 tackles, one tackle for loss and 10 quarterback pressures with no sacks in six games this year.
He has missed seven games because of ankle and groin injuries. A plantar fasciitis injury kept him out of much of the team's offseason program and training camp.
Ratliff signed a five-year, $40 million contract extension last year, with $17.5 million of it guaranteed. His salary will count $7 million toward next year's cap.
