An eye-opening detail emerges on Auburn's contract extension to Gus Malzahn

This is surprising.

Auburn coach Gus Malzahn has a new seven-year, $49 million contract extension in the works, but it's "definitely not" fully guaranteed and hasn't officially been signed, according to Auburn president Steven Leath via AL.com.

Leath, who introduced Allen Greene as the school's new athletic director on Friday, confirmed that both sides were still working on the details of Malzahn's new deal.

"We actually haven't signed (Malzahn's contract) either," Leath said. "We're still working through the final details. I'm still a trust guy and Gus and I are functioning well together. We know the basic tenets, we've drawn things up, sent it to his attorney. We'll get that cleaned up pretty soon."

Leath claimed the percentage of completion was "above 50, but well under 100" and said "it is definitely not" fully guaranteed when asked by reporters.

Malzahn reportedly agreed to an extension in December, according to 247Sports. The former SEC Coach of the Year spent the past five seasons at Auburn, which includes a 45-22 (25-15 SEC) overall record, one conference championship, two SEC West division titles and a BCS National Championship Game appearance during his first season as head coach.

The Tigers finished with a 10-2 (7-0) record during the 2017 regular season, before losing to Georgia in the SEC Championship Game and UCF in the Peach Bowl.
