The Minnesota Vikings will hire Mike Zimmer as coach, a league source told ESPN.
The Vikings and Zimmer, who spent the past five seasons as the Cincinnati Bengals' defensive coordinator, had been in negotiations in an effort to complete a deal Wednesday, according to league sources.
Zimmer remained overnight after his second interview Tuesday was finished, with Vikings owner Zygi Wilf more centrally involved in the session, sources told ESPN.
Wilf made calls to selective references on Zimmer and came away satisfied to give a green light on hiring him to succeed Leslie Frazier as Minnesota's coach.
Parameters of a contract were in place, and negotiations between the Vikings and Zimmer's agent, Marvin Demoff, gained momentum toward completion, league sources told ESPN.
After surrendering the second-most yards and the most points in the NFL this season, the Vikings are turning to a head coach they believe can help fix those problems.
Vikings star running back Adrian Peterson said he was not surprised by Minnesota's choice of Zimmer.
"I've been keeping my eyes open with the head coach," Peterson told ESPN. "I knew (Zimmer) was probably the guy they were going to go with. It wasn't too much of a surprise."
Zimmer will have his work cut out for him. The Vikings had the worst opponent Total QBR (67.4) of any team during the Frazier era (2011-13), according to ESPN Stats & Information.
Zimmer will become the ninth coach in franchise history, 16 days after Frazier was fired on the heels of a 5-10-1 season. He goes to Minnesota after directing a Bengals defense that finished in the top 10 in yards and points allowed in four of the past five seasons.
Peterson, who acknowledged to ESPN that he was "disappointed" by Frazier's firing, said he will closely monitor the Vikings' direction as a franchise.
"Trust me, I'm watching," he told ESPN. "I'm watching to see exactly what we're doing, just to see exactly what direction we're headed in. ... With a new coach, that's when things start happening, too. That's all part of the process."
Zimmer had been targeting Bengals linebackers coach Paul Guenther as his defensive coordinator, sources told ESPN. But the Bengals acted quickly Wednesday, promoting Guenther to defensive coordinator, according to sources.
Guenther met Wednesday with Bengals owner Mike Brown and agreed to a three-year deal to stay with Cincinnati, according to a source.
Zimmer, 57, is considering hiring Cleveland Browns offensive coordinator Norv Turner as his offensive coordinator, a league source told ESPN. The Vikings have received permission to interview Turner, a source said. Zimmer also is considering Kyle Shanahan and Mike Mularkey as candidates, according to league sources.
Vikings tight end Kyle Rudolph took to Twitter on Wednesday to express his excitement over the pending hire of Zimmer.
