MIAMI (AP) — Coach Adam Gase's new backup quarterback in Miami is his former backup quarterback in Denver.

Brock Osweiler signed a one-year contract Friday with the Dolphins to provide veteran insurance behind Ryan Tannehill, who is coming back from two knee operations.

Gase was an assistant with the Broncos when Osweiler was a young reserve for them in 2012-14. Osweiler went 0-4 as the Broncos' starter last season and has 25 career starts in six NFL seasons.

With the Dolphins he replaces Matt Moore, a free agent after seven years as their backup quarterback. Despite adding Osweiler, the Dolphins will consider drafting a quarterback next month.

Tannehill is expected to return after missing all of the 2017 season, but he has twice had surgery since his most recent game.

The Dolphins made two other moves to upgrade their offense. Five-time Pro Bowl running back Frank Gore finalized a deal with his hometown team after agreeing to terms Thursday. Tackle Sam Young agreed to terms on a one-year contract to remain with the Dolphins, two people familiar with the negotiations said.

Gore, who turns 35 next month, has rushed for 14,026 yards to rank fifth on the all-time list. He spent the past three seasons with the Indianapolis Colts, and ran for 961 yards last season.

Young, an eight-year NFL veteran, started six games at right tackle for the Dolphins last year after Ja'Wuan James was hurt. He's expected to be James' backup again this season.
