Last week, there was speculation that Steelers long-time linebackers coach Keith Butler was a likely candidate to be the defensive coordinator in Tennessee under new head coach Ken Whisenhunt, a former offensive coordinator under Bill Cowher in Pittsburgh, who served on the same staff as Butler for several seasons.

This week, there is more than speculation that Steelers running backs coach Kirby Wilson could leave for the offensive coordinator job in Baltimore. It was reported on Tuesday by several outlets– including ESPN.com–that Pittsburgh has given Ravens coach John Harbaugh permission to interview Wilson this week in Mobile, Alabama, while both coaches are in attendance for the 2014 Senior Bowl.

Wilson, who was once considered a likely successor to Bruce Arians, would never get his chance after a house fire in January of 2012 left him severely burned and incapacitated for several months, while he recovered from his injuries.

Instead, after Arians and the team parted way, weeks after Wilson suffered his accident, Todd Haley was hired as the new offensive coordinator, and has held the position for the past two seasons.

• Wilson returned to the team for the start of the 2012, remaining running backs coach, through 2013.

The OC job opened up in Baltimore, after Jim Caldwell, who was hired near the end of the 2012 season to replace a fired Cam Cameron, was named  the Lions new head coach last week.
