The Bears worked out a contract extension Thursday — just not with the two prominent players who they’d been in negotiations.

Nose tackle Andrew Billings, who’s been one of the Bears most steady players since the team signed him to a one-year deal this offseason, agreed to two-year extension, a source said. He’ll be under contract until 2025.

Billings spent the first three years of his career with the Bengals, then a year apiece with the Browns and Raiders. He started all 14 games in which he played last year, and has started all eight games this season.

“We’re extremely excited to be able to keep Andrew in Chicago,” general manager Ryan Poles said in a statement. “The professionalism, dependability and toughness he brings to our defense exhibit the type of player we want in our organization.”

It’s hard to measure interior defensive linemen with statistics, but the Bears have praised his play all season.

Poles is also trying to negotiate an extension with edge rusher Montez Sweat, for whom he traded Tuesday. Cornerback Jaylon Johnson’s camp had negotiated for a new deal with Poles up until Monday, when they, unsuccessfully, asked for a trade.
