Norv Turner has resigned as Vikings offensive coordinator.
Pat Shurmur will be the interim offensive coordinator for the rest of the season, the team announced Wednesday morning. Turner, in his 27th season as an NFL coach, had called plays for the Vikings in 40 games under head coach Mike Zimmer.
Zimmer said that Turner's job status was not in jeopardy and that he was "surprised" when Turner came into his office at 6:30 Wednesday morning to share his decision.
"There was no thought of making any kind of change," Zimmer said. He added: "I wasn't going to make a change. I had no indication that this was going on."
Quarterback Sam Bradford was equally stunned.
"I obviously didn't see this coming," Bradford said.
Turner told ESPN's Ed Werder that he and Zimmer had opposing opinions on the offense.
