South Carolina coach Steve Spurrier retiring, effective immediately

— -- South Carolina coach Steve Spurrier told his players and coaches Monday night that he is retiring immediately, sources told ESPN.com. The plan is for someone else to coach the team the rest of the season.

Spurrier's retirement was first reported by SI.com.

An interim coach will be named Tuesday, sources said.

Spurrier, the Gamecocks' all-time winningest coach, also informed South Carolina athletic director Ray Tanner of his decision to step down, sources said. This came after the Gamecocks lost their fourth straight SEC game Saturday to LSU. The loss guaranteed Spurrier no better than a .500 season. He has never had a losing season in 25 seasons coaching in college.

Spurrier, 70, was close to stepping down at the end of the past season, after the Gamecocks dipped to 7-6 on the heels of three straight 11-win seasons and three straight top-10 finishes, but he elected to return. The Gamecocks have lost eight of their past nine SEC games dating to the past season.

The Gamecocks are 2-4 overall this season and 0-4 in the SEC. They sit seventh in the SEC East.

One possibility to coach the Gamecocks the rest of the season is defensive coordinator Jon Hoke, who is in his first season with the Gamecocks. He was brought in after South Carolina struggled on that side of the ball last season. Other possibilities are quarterbacks/tight ends coach G.A. Mangus and co-offensive coordinator/offensive line coach Shawn Elliott.

Spurrier, fed up with the age questions and critics suggesting his best coaching days were behind him, went on the offensive before this season began.

"We were 11-2 and ranked fourth in the country this time a year ago, and nobody said a damn word about my age," Spurrier said. "Now, a year later, I'm suddenly too old, and we're on our way down.

"I just want our fans to know that we're going to have a good team and recognize that it's our enemies saying these things about Spurrier being washed up and we're not going to be heard from again. Gamecocks out there need to know that I'm going to be here five or six more years, and away we go."

Spurrier said then that he wasn't going to let one down season derail the momentum the program had built since going to the SEC championship game in 2010. Before he arrived in 2005, South Carolina had one season of double-digit wins in its history.

"I'm smart enough to know when it's time to let somebody else come in and do this, but I'm also smart enough to know that we've beaten Georgia four of the last five years, beaten Florida four of the last five years and beaten Clemson five of the last six years," Spurrier said in July. "We're only 3-2 against Tennessee the last five years, and they won a couple of close ones against us, but they've lost 10 in a row to Florida. So I'd say we've done OK and have a lot more we're going to do."

Spurrier has an 86-49 record at South Carolina and a 228-89-2 mark in 25 seasons as a head coach. He coached Florida, his alma mater, from 1990 to 2001 and led the Gators to the 1996 national championship and six SEC championships. He has been named SEC coach of the year nine times.

In addition, Spurrier had brief stints at Duke and with the NFL's Washington Redskins.

He won the 1966 Heisman Trophy as Florida's quarterback.

Spurrier became South Carolina's winningest coach, with 65 victories to surpass Rex Enright, in the 2012 season finale. He also is Florida's winningest coach (122 victories), and he and Paul "Bear" Bryant are the only coaches to record the most wins at two different SEC schools. Only Bryant, at 159, has more SEC wins than Spurrier's 135.

The Gamecocks play at home against Vanderbilt (2-3, 0-2) on Saturday.
