IRVING (105.3 THE FAN) -- The Dallas Cowboys are continuing to shuffle their coaching staff's "second level" with what sources tell 105.3 The Fan will be the addition of both long-time NFL offensive line coach Steve Loney and former Cowboys offensive lineman Marc Colombo, both of whom will work under elevated line coach Frank Pollack.

Pollack last year served as an aide to the departed Bill Callahan (now in Washington). Special assistant Monte Kiffin is also not returning.

Loney, most recently at Arkansas, has an impressive resume from years coaching in the NFL, including his working with Cowboys offensive coordinator Scott Linehan during his time with the Vikings.

Colombo is a favorite of head coach Jason Garrett and has spent the last year in the Cowboys scouting department.
