Ken Whisenhunt closing in on a decision

Ken Whisenhunt appears to be closing in on a decision.

ESPN Insider Adam Schefter reported Monday morning that Whisenhunt, long believed to be the favorite for the Detroit Lions job and the Lions' favored candidate, will probably make up his mind in the next couple of days.

“Ken Whisenhunt really is the next big domino to fall,” Schefter said on "SportsCenter" this morning. “Within the next 48 hours, he is likely to choose from one of the head coaching opportunities that are out there, that he’s been in discussion with.”

Schefter said the Lions have been one of the teams in the discussion and he is still the favorite with the team.

However, Schefter said Tennessee “shouldn’t be discounted” when it comes to vying for Whisenhunt’s services.

The San Diego offensive coordinator is now available to be hired because the Chargers were eliminated from the playoffs Sunday by Denver.

Whisenhunt interviewed with Detroit last Thursday, Tennessee last Friday and Cleveland last Saturday. Prior to his job in San Diego, he was the head coach in Arizona from 2007 to 2012, finishing with a 45-51 record but leading the Cardinals to Super Bowl XLIII. Pittsburgh beat Arizona in that game, 27-23.

Detroit has also interviewed Baltimore offensive coordinator Jim Caldwell, former Tennessee head coach Mike Munchak and former Houston head coach Gary Kubiak for the position vacated when the Lions fired Jim Schwartz on Dec. 30.
