In July, Nixon, a 6-foot-6, 285-pound offensive tackle from Fayetteville (N.C.) Britt, narrowed his list of 40-plus scholarship offers to Clemson, Florida, LSU, Miami, North Carolina, NC State, Notre Dame, South Carolina, and West Virginia.
Nixon says his next cut will "probably" eliminate all but three schools from contention.
"Florida and LSU, those are probably the only two definite ones [to make the cut to three]," Nixon said.
Vying for the final spot are Clemson, Miami, and in-state schools UNC and NC State.
Of the four schools competing for his final spot, Nixon said he has been most impressed by the play of UNC, which is 3-1 after a last minute victory over Miami.
"They've been playing well lately," Nixon said. "Butch [Davis] is doing a great job with the team and they're definitely on the come up."
Nixon said he caught "some" of the UNC-Miami game Saturday.
"It was very impressive the way they preformed and pulled out the victory," Nixon said.
During the weekend of Sept. 5, Nixon officially visited Florida.
"I enjoyed myself," Nixon said. "I really liked the atmosphere of the game. The team was very mature – I liked that. The way they spoke in the locker room, it showed a lot of leadership."
Nixon also has an official visit scheduled with LSU on October 25.
Nixon hasn't begun official visit talks with any other schools. However, he says the school that wins the last spot on his final three list will be granted his third and final official visit.
After taking his three official visits, Nixon plans to announce his verbal commitment during the U.S. Army All-American Bowl on Jan. 3.
"I'm looking for a place where I can get a great degree and play early," Nixon said.
