The Indianapolis Colts hired Bruce Arians to serve as the team's offensive coordinator on Tuesday.

Later in the day, the Colts also named Harold Goodwin as its offensive line coach.

The 59-year-old Arians has spent the last five seasons in charge of the Pittsburgh Steelers' offense.

He had officially retired before accepting a position with the Colts. Rumors have swirled that Arians was forced out of Pittsburgh as the team looks to return to its past run-first mentality.

The Steelers finished 12th in the NFL in offense last season.
