Favre said despite the team's 3-7 record and turmoil under Frazier's fired predecessor, Brad Childress, he'll give it his all for the rest of the season, KSTP-AM in St. Paul, Minn., reported on its Web site.
"Make that clear: I want to finish on a high note if my body will allow me and I can play up to my expectations, my standards," the Vikings signal caller said. "I want to do it."
He added he never meant to imply in words uttered after Minnesota's decisive loss to Green Bay last weekend that he was hanging it up for the year.
Vikings owner Zygi Wilf fired Childress after the defeat.
"I want to get this team back on track and that's my goal," Favre told reporters.
