The Houston Texans are expected to interview Ken Whisenhunt for their head coaching vacancy as soon as possible.

Whisenhunt and Texans' general manager Rick Smith are familiar with each other from working together on the NFL's competition committee for a year. The two formed a bond and have stayed in touch.

Whisenhunt is offensive coordinator of the San Diego Chargers and led the Arizona Cardinals to the Super Bowl in the 2008 season.
