The reigning Super Bowl champions continue to make sure their biggest stars aren’t going anywhere.

The Kansas City Chiefs have agreed to terms with tight end Travis Kelce on a four-year contract extension worth $57.25 million.

Kelce’s deal includes $28 million in guaranteed money.

The reported extension will keep Kelce under contract through the next six seasons. The five-time Pro Bowler was previously signed through 2021 after inking a five-year extension in 2016.

Kelce’s reported deal makes him the second-highest-paid tight end in NFL history. He trails only George Kittle, who reached an agreement with the San Francisco 49ers on a record five-year, $75-million extension Thursday. Kittle is set to earn $15 million per season under his new deal.

Kelce, 30, has racked up at least 80 catches and 1,000 receiving yards in each of the last four seasons, including a 103-reception, 1,336-yard, 10-touchdown campaign in 2018.

Kansas City already extended quarterback Patrick Mahomes and defensive lineman Chris Jones earlier this offseason. Mahomes inked the biggest contract in sports history while Jones become one of three interior defensive linemen to earn an average annual salary of at least $20 million.
