NEW YORK (AP) The Associated Press has obtained a letter sent to Jerry Jones' attorney accusing the Dallas Cowboys owner of "conduct detrimental to the league's best interests" over his objection to a contract extension for NFL Commissioner Roger Goodell.
The letter accusing Jones of sabotaging the negotiations was sent to David Boies on Wednesday.
Jones hired Boies and threatened to sue the NFL if Goodell's contract extension was approved by the compensation committee, made up of six owners.
All 32 owners voted unanimously in May to let the committee finalize a deal with Goodell.
The letter, first reported by The Wall Street Journal, was written by outside counsel for the compensation committee and given to the AP by a person who requested anonymity because it was not intended to be made public.
It's the latest escalation of a feud between the NFL and one of its most powerful owners.
Jones has denied that his objections to the extension are tied to Goodell's decision to suspend star running back Ezekiel Elliott for six games over alleged domestic violence.
