A year ago, the Tigers lost Gene Chizik, who left for a post at the University of Texas.
Chizik's replacement, David Gibbs, is considering offers from NFL teams, Tuberville said. Gibbs coached secondary with the Denver Broncos prior to coming to Auburn.
"David has been contacted by at least a half dozen NFL teams," Tuberville said. "We visited last week about it. He doesn't know whether college or pro is what he wants to do, but I told him we are supportive of what he wants to do.
"The next few days he will visit a couple teams to see if there is any interest that he is wanting to get back into the NFL. There are several that I think might interest him a little bit more than others because of personal situations, but we should have an answer by this weekend.
Coaches Tuberville, Gibbs and defensive line coach Don Dunn are shown during an AU contest.
"We would love for David to stay," Tuberville adds. "He has done a great job for us, but I don't want anybody on my staff that doesn't have aspirations of the future in whatever they want to do.
"He did a good job for us so we will probably know by the weekend if there is anything...if we are looking for another defensive coordinator, but right now he is still with us. He recruited all the way through. He was at all of our meetings today. That is going to be up to his wife and himself what he is going to do in the future."
The Tigers finished sixth in the SEC and 19th nationally in total defense, allowing 315.25 yards per game. The Tigers were ranked third in the SEC and sixth nationally in scoring defense with an average of 15.5 points per game allowed.
Gibbs, who also coaches the secondary, saw his team finish seventh in the SEC and 32nd nationally in passing yards allowed at 199.0 per contest.
