HAMPTON, Ga. -- 23XI Racing, the NASCAR team co-owned by Michael Jordan, said Saturday that it had skipped a deadline to sign a new charter agreement with the sanctioning body because "it did not have an opportunity to fairly bargain" for a new contract.

The two-car team owned by Jordan, active driver Denny Hamlin and Curtis Polk -- Jordan's right-hand man -- revealed that teams had a Friday night, NASCAR-imposed deadline to sign new charter agreements that run from 2025 through 2031.

In a letter to NASCAR, 23XI said it was refusing to sign the extension. The team's revelation came on the eve of the start of NASCAR's playoffs as garage speculation Saturday indicated that all but two Cup Series teams have signed the new agreements.

But three people speaking to The Associated Press on condition of anonymity because of the sensitivity of the yearslong negotiations said the teams felt "threatened and coerced" by NASCAR to sign the extensions or risk them being revoked. They spoke on condition of anonymity to avoid putting their agreements as risk.

Last week, Polk pinned a sheet of paper to the back of his shirt that read: "Please don't ask me about my Charter. I don't want to disparage NASCAR and lose it." He wore it during the Southern 500 at Darlington Raceway, where 23XI Racing driver Tyler Reddick became the regular-season champion and the team said no one from NASCAR bothered to present him with the trophy.

"We notified NASCAR what issues needed to be addressed, in writing, at the deadline," 23XI said in its statement. "We are interested in engaging in constructive discussions with NASCAR to address these issues and move forward in a way that comes to a fair resolution, while strengthening the sport we all love."

The playoffs begin Sunday at Atlanta Motor Speedway.

There are currently 36 charters in NASCAR for a 40-car field each week in the top-level Cup Series. A charter guarantees the 36 cars entry into all 38 races each season and a portion of the television package and purses depending on each team's charter value.

Four charters remain held back by NASCAR, earmarked for a future manufacturer that might join Chevrolet, Ford or Toyota in the Cup Series. A summer proposal from NASCAR suggested those charters should go to NASCAR and that the France family that runs the series should be able to field teams.

Hamlin, in his weekly podcast, said NASCAR's newest proposal included an anti-disparagement clause.

The most recent charters were signed in 2015 and run through the end of the year, when the current television packages expire. Negotiations have been ongoing for more than two years, with teams content to allow NASCAR to negotiate a new media package first so they have a clear idea how much money will be coming.

The teams want a bigger share of the revenue pie, a seat at the negotiating table and for charters to become permanent. NASCAR has refused to even entertain that charters become permanent.
