The NFL is seeking more than $1 billion from its insurers to cover the cost of the class-action concussion settlement, the insurance firms disclosed in recent court documents.
That would cover much of the estimated $1.4 billion settlement that was struck in 2013 and has survived a series of legal challenges, most recently in 2016.
The insurers and the league are embroiled in a legal struggle as the insurance companies seek to avoid covering the settlement.
They contend the NFL knew about the risks of head trauma and so that negates the policies.
Neither the league nor the insurers had publicized how much the NFL wants from its carriers until the recent disclosures. In two separate legal filings earlier this month, the companies unveiled the amount.
