The Kansas City Chiefs and Creed Humphrey have agreed to a four-year, $72 million contract extension, according to multiple reports, making him the highest-paid center in NFL history.

Humphrey is reportedly getting $50 million guaranteed in his new deal. Those figures far exceed the combined value of the five-year, $60 million deal the Saints signed with Erik McCoy and the $42 million in guarantees Frank Ragnow received in his four-year, $54 million deal with the Lions.

Humphrey was selected by the Chiefs in the second round of the 2021 draft and was immediately inserted into the starting lineup, where he not only solidified the interior of a rebuilt offensive line but also developed a quick rapport with quarterback Patrick Mahomes.

He has also proven reliable, starting all 51 regular-season games over the past three seasons. The last two seasons ended with Humphrey earning trips to the Pro Bowl, which he missed while helping the Chiefs win back-to-back Super Bowls.

The Chiefs are eyeing the prospect of three key players from their 2021 draft class becoming free agents: Humphrey, Nick Bolton, who was also a second-round pick, and Trey Smith, who was a sixth-round pick. They have expressed interest in signing Bolton, one of the league’s most underrated quarterbacks, to a long-term deal, but retaining all three could be difficult given the salary cap.

Humphrey and most of the Chiefs’ starters sat out Thursday night’s preseason finale against the Bears. They open the regular season against the Ravens on Sept. 5 in a rematch of the AFC finals.
