The NFL says former Brown coach Hugh Jackson’s allegations that he was paid to lose matches cannot be verified.

A statement issued by the association today said that an independent investigation found no substance to these allegations. It also said that Jackson initially said he would cooperate with the investigation but then chose not to.

“After a 60-day independent review of comments made by former Cleveland coach Hugh Jackson that paid or provided Brown incentives to lose games during the 2016-2017 seasons, former US attorney and Securities and Exchange Commission Chairman Mary Jo White and a team of attorneys from Debevoise decided that no None of the allegations can be substantiated,” the NFL said in the statement.

“The investigation found no evidence to suggest that Brown’s quartet plan, club ownership or football staff sought to cause or incentivize losses and did not make any decisions deliberately to weaken the team to secure a more favorable position.

The comprehensive review included the full cooperation of the Brown family and interviews with Jimmy Hassan and current and former members of the organization. While Coach Jackson initially agreed to meet with investigators, he eventually did not.

“Although not able to speak directly to coach Jackson, the Debevoise team had access to his public statements, files and testimony in previous arbitration proceedings. The club also produced thousands of pages of documents, including emails, texts, internal memos and presentation tables as well as to other materials relating to club operations, registrations and testimonies in arbitration proceedings between the club and coach Jackson.

Similar allegations made by former Dolphins technical director Brian Flores are still under investigation.
