MINNEAPOLIS (AP) — The Minnesota Vikings have fired offensive coordinator John DeFilippo, the former Eagles quarterbacks coach whose first season on the job ended after just 13 games amid a sharp decline in production by the offense over the past six weeks.

Vikings quarterbacks coach Kevin Stefanski, who played for St. Joseph’s Prep and then Penn, was named interim offensive coordinator on Tuesday morning, after a 21-7 loss at Seattle on Monday night. Stefanski will take over the play-calling duty from DeFilippo, whose work with new quarterback Kirk Cousins didn’t materialize into consistent success.

The Vikings (6-6-1) have been held to fewer than 300 yards in four of their past five games. They’ve scored an average of 12.8 points in those four games.

Stefanski has been an assistant coach with the Vikings since 2006, surviving two head-coaching changes.

DeFilippo joined the Eagles in the 2016 preseason and left for the Vikings post.
