Bud Grant has resigned as head coach of the Minnesota Vikings for the second time and will be replaced by Jerry Burns, an assistant coach, Vikings General Manager Mike Lynn said today.

Grant returned as coach last season after a self-imposed one-year retirement. He had been the Vikings' coach for 17 years before he quit after the 1983 season.

Les Steckel was promoted to head coach in 1984, but the team finished at 3-13, its worst record ever. Grant was lured back to help return the team to respectability, and this season the Vikings were 7-9.

"With the infusion of new players we had, and some of our new staff members, it was probably as enjoyable a season as I've ever had," Grant said. But he added that he was frustrated by the Vikings' five losses by narrow margins.

Grant said he decided Dec. 28 to step down again. He cited the same reason for leaving this time as he did in 1983: He wanted to spend more time with his family.

"I signed a year-to-year contract," Grant said. "We had decided if I did not want to coach, I would not be back.

"I think the club is in a little better shape than it was a year ago," he added. "I think they need a coach who is going to be here for an extended period of time."

Grant, 58, led the Vikings to four Super Bowls, and his teams compiled a regular-season record of 158-96-5.

Burns, who will be 59 later this month, has been with the Vikings since 1968, serving as offensive coordinator. He joined the team after working two years as the defensive backfield coach with Green Bay. He also worked at the University of Iowa for 12 years, seven as an assistant and five as head coach.
