The Eagles and defensive tackle Fletcher Cox have agreed to a contract extension that includes the largest guarantee for a player other than a quarterback in NFL history, ESPN’s Adam Schefter reported Monday.

Per Schefter, it’s a six-year extension worth up to $103 million with $63 million guaranteed.

Cox, 25, went to his first Pro Bowl last season. He hasn’t missed a game over the last three seasons while becoming one of the most dominant interior players in the game. Cox had 9.5 sacks last season and has 22 over his four-year career.

The Eagles confirmed on their official Twitter account that the sides have agreed to an extension. Cox had one season left on his previous deal.
