ENGLEWOOD, Colo. (AP) — A person with knowledge of the negotiations tells The Associated Press that the Denver Broncos have upped their offer to Von Miller by offering to guarantee a record $70 million of the six-year deal.

The person spoke to the AP on condition of anonymity to share candid details of the blockbuster offer, which was also reported by ESPN and the NFL Network.

The sides agreed to the parameters of a $114.5 million deal last month but Miller's camp rejected Denver's offer of $38.5 million in guarantees.

GM John Elway's offer now surpasses the $63 million in guarantees that Philadelphia's Fletcher Cox received last month and represents the most money ever offered a non-quarterback.

The sides have until 4 p.m. EDT Friday to get a signed deal into NFL headquarters.
