The Pittsburgh Steelers have signed coach Mike Tomlin to a three-year extension, the team announced Monday.

Tomlin, 52, said in January that he expected to get an extension this offseason.

His extension puts him under contract through the 2027 season.

The Steelers haven’t had a losing season in his 17 years as the team’s head coach, an NFL record. He has a 173-100-2 regular-season record and is 8-10 in the postseason as Pittsburgh’s coach.
