Chuck Pagano and Ryan Grigson will be paired together for four more years in Indianapolis.

Colts owner Jim Irsay announced Monday at a hastily-called, late-night news conference that he had given his coach and general manager contract extensions.

Pagano, the 55-year-old coach, received a four-year deal to replace the expiring contract that prompted speculation he could be ousted Monday. Grigson got three years added to the one year he had on the original deal he signed in 2012.

Financial details were not immediately available.

Pagano led the Colts to the playoffs in his first three seasons in charge, losing in the 2014 AFC Championship Game. But plagued by injuries, including to star quarterback Andrew Luck, Indianapolis went 8-8 this season as Houston won the AFC South.
