Fisher guided the No. 1 Seminoles (13-0) to a spot in the ACC championship game, where they beat No. 20 Duke 45-7 on Saturday night to likely clinch a spot in the VIZIO BCS National Championship next month.

Fisher's current deal pays him $2.75 million. The new deal would put him among the highest paid coaches in the country.

Florida State athletic director Stan Wilcox confirmed that a new deal with Fisher had been reached but said details were still being finalized.

"Throughout the year, it was important to take a look and see what was going on, and as we continued to improve on the field and do very well, it was time to talk," Wilcox said after the Seminoles' win Saturday night. "I didn't want to distract Jimbo from his task, so I was able to talk with his agent and we were able to work out and come to a pretty mutual agreement on things, and now we're in the process of finalizing."

Fisher is 44-10 since replacing Bobby Bowden as the Seminoles' head coach four years ago. He previously served as the team's offensive coordinator.

Florida State entered the season No. 11 in the Associated Press poll, but climbed the rankings all year.
