The Vikings announced Monday morning that Leslie Frazier will not return as coach in 2014.

“We have tremendous respect and appreciation for Leslie and what he has done for the Minnesota Vikings,” said Vikings owner Zygi Wilf. “He stepped in and established a strong positive culture here and he has been the consummate professional as our head coach and in this community. Making this change is difficult, but what we determined is best for the organization.” “Unfortunately, we did not achieve consistent success and did not achieve the progress we expected,” said Vikings General Manager Rick Spielman. “We believe a coaching change is needed to help build a successful team moving forward.”

CBS Sports NFL Insider Jason La Canfora wrote Sunday that the Vikings began back channeling with coaching candidates -- Penn State's Bill O'Brien among them -- several weeks ago, and, having not extended Frazier's contract a year ago and with him coaching out his option year, it was widely expected that he would be let go.

Frazier, who took over for Brad Childress during the 2010 season, amassed a 21-32-1 record in Minnesota.
