Ben Roethlisberger and the Pittsburgh Steelers have agreed to a contract extension through the 2021 season.

Roethlisberger had one year left on a four-year, $87.6 million deal he signed in 2015. 

The deal will essentially guarantee Roethlisberger retires with the NFL.

Pittsburgh has lost both Antonio Brown and Le'Veon Bell this offseason amid questions of Roethlisberger's leadership.
