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.

The San Francisco 49ers and their star QB Brock Purdy may be in "up-next'' mode as they try to reach an agreement on a new contract.

Brock Purdy already preparing for next NFL season as the San Francisco 49ers deliver major update on key teammate.
