"Not only do the Indianapolis Colts plan to add former Steelers offensive coordinator Bruce Arians to their staff, but Indianapolis also plans to hire Keith Butler, Pittsburgh's linebackers coach, as its defensive coordinator, according to league sources.

Butler is planning to fly to Indianapolis on Tuesday to review and sign the contract that will make him a part of former Ravens defensive coordinator and current Colts head coach Chuck Pagano's staff.

Arians is scheduled to fly to Indianapolis on Monday to review and sign the contract. The Steelers had said he "retired" from his post but he confirmed last week that the team actually let his contract expire and he was still listening to coaching offers."
