Dallas Cowboys owner Jerry Jones has reportedly hired attorney David Boies in an effort to prevent NFL commissioner Roger Goodell's contract extension, according to the New York Times. Jones has allegedly threatened to sue the league, as well as some team owners, if Goodell's extension is approved by the league's compensation committee.

Jones, who is not on the league’s compensation committee to negotiate Goodell's deal, is one of "four or five owners" who believe Goodell should not continue as commissioner, according to ESPN.

Additionally, ESPN notes there are another half-dozen owners who were called "fence-sitters" by one source, and they're the group that Jones wants Boies to target.

Per the New York Times,

"Jerry Jones, the owner of the Dallas Cowboys and one of the N.F.L.’s most powerful figures, has escalated his feud with Commissioner Roger Goodell, threatening to sue the league and some fellow team owners over negotiations to extend Goodell’s contract, according to two people with direct knowledge of the situation."

"Jones told the six owners on the league’s compensation committee last week that he had hired David Boies, the high-profile lawyer under fire in the Harvey Weinstein sexual harassment case, according to the people, who declined to be speak publicly about internal league matters."

The New York Times report alleges that during a conference call last Thursday, Jones informed the six owners on the compensation committee— those of the Chiefs, Falcons, Giants, Patriots, Steelers and Texans — that legal papers were drawn up and would be served this Friday if the committee did not scrap its current plans to extend Goodell’s contract.
