The $76 million deal heading George Kittle's way is an important line in the sand for the San Francisco 49ers.

NFL Network's Ian Rapoport reported on Tuesday that Kittle and the 49ers agreed to terms on a four-year, $76.4 million extension that will make him the league's highest-paid tight end. The 49ers entered the day with $39.4 million in cap space, not accounting for any potential changes to Kittle's cap number with his new contract.

Humphries—age 31—spent his first nine seasons with the Arizona Cardinals, who selected him with the 24th overall pick in the 2015 NFL Draft. He earned Pro Bowl honors in 2021, but tore his ACL in December of '23 and was released ahead of the '24 season. Humphries signed a one-year deal with the Kansas City Chiefs last November.
