The ceremony included remarks from athletic director Jay Jacobs, president Jay Gogue, Gene Chizik, Pat Sullivan, Bo Jackson and Cam Newton.
The statues were created by Ken Bjorge, a self-taught sculptor from Bigfork, Montana.
After remarks by Jacobs, Gogue and Chizik, Sullivan, who won Auburn's first Heisman Trophy in 1971 after passing for 2,012 yards and 20 touchdowns that season, took to the podium. Sullivan recounted his experience of winning the Heisman Trophy in 1971, including the memory of being told "You won't be known as Pat Sullivan (anymore). You'll be known as former Heisman Trophy winner Pat Sullivan." Sullivan said it's the relationships he built at Auburn are what last a lifetime.
An All-American in 1970 and 1971, Sullivan passed for 6,284 yards and 53 touchdowns in his career at Auburn.
Jackson, who won the Heisman Trophy in 1985 after rushing for 1,786 yards (162.4 per game) and 17 touchdowns, took to the podium next.
Jackson said he didn't do speeches, so he just spoke from the heart, which is advice he said he got from former coach Pat Dye.
Jackson shared his most memorable moment from his time at Auburn. He said it was when he found his mother and embraced her after the 1982 Auburn/Alabama game.
He finished his time at Auburn as the only tailback in Auburn history to rush for more than 4,000 yards in a career.
A two-time All American and three-time All-SEC selection, Jackson was a standout in football, baseball and track for the Tigers.
Auburn's 2010 Heisman Trophy winner was the last to speak. Newton threw for 2,854 yards and 30 touchdowns and ran for 1,473 yards and 20 more scores as he led Auburn to a perfect 14-0 record, an SEC Championship and the 2010 BCS National Championship. Newton also won the Davey O'Brien Award, the Maxwell Award and the Walter Camp National Player of the Year Award.
As a first-year starting quarterback for the Carolina Panthers last season, Newton was named the NFL Rookie of the Year after breaking Peyton Manning's record for most passing yards by a rookie quarterback.
Cam spoke about how fondly he remembered his time at Auburn and finished his remarks with the following poem:
365 days that was my tenure
But for some strange reason it felt like I've always been here.
All the blood, sweat and tears it took to get this
I'll always honor and cherish this.
My road to the top had a couple pit stops
But during my time at Auburn the love of the Auburn family would not let my morale drop.
Greatness was what I strived for and greatness is what I got
The mentality of the Auburn man took me to the top
Some people will never understand the feeling of what it means to be an Auburn man
But I'm lucky enough to be able to raise my right hand and be able to say "I can."
My time at Auburn, I don't know if it could have been any better
Man, was it great.
We won an SEC title, a national championship
And, oh yeah, we beat that team, 27-28
As a wise man once said, "This place," as in Auburn, "was great way before you were thought of" (Coach Chizik)
And this place is where I will always love
So as I share this day with two of Auburn's beloved
I want to end by saying "War Eagle" and "I believe in Auburn and love it."
After Newton finished speaking, the Heisman Trophy winners took turns unveiling statues in their likenesses. Sullivan's statue depicts the 1971 Heisman winner throwing a pass. The statues of Jackson and Newton depict the two running with the football.
