Owner Arthur Blank and general manager Rich McKay are expected to interview Steelers offensive coordinator Ken Whisenhunt for the Falcons' head coaching vacancy on Thursday. Blank fired Jim Mora, who went 26-22 in the last three seasons, on Monday. The Steelers gave permission to Whisenhunt and Steelers offensive line coach Russ Grimm to discuss job openings with other NFL teams searching for a new head coach.
