Mike Zimmer plans to be more involved with the offense in the wake of the Minnesota Vikings firing of offensive coordinator John DeFilippo.

DeFilippo was fired after Monday night's 21-7 loss to the Seattle Seahawks.

"At the end of the day, it is a production business," Zimmer said. "It's difficult. It's hard thinking about it, hard making the decision, hard trying to. I have a lot of respect for John. I think he is a very, very brilliant mind. But we weren't producing is the end of it."

Quarterbacks coach Kevin Stefanski will take over offensive coordinator duties on an interim basis.

The Vikings are on the cusp of the postseason, slotted as the sixth seed in the NFC playoff picture with three games remaining.
