Ole Miss
In April 2025, Chambliss announced his decision to transfer to the University of Mississippi to play for the Ole Miss Rebels.[7][8] He entered the season as the backup to Austin Simmons.[9] In the season opener against Georgia State, he completed four passes for 59 yards and a touchdown.[10] Following an injury to Simmons, Chambliss was named the Rebels' starting quarterback against Arkansas.[11] In his first start for Ole Miss, he combined for 415 total yards and three touchdowns in a 41–35 triumph over Arkansas.[12] In the Egg Bowl against Mississippi State, Chambliss completed 23 passes for 359 yards and four touchdowns, leading the Rebels to a 38–19 victory and clinching a spot in the College Football Playoff.[13] At the conclusion of the regular season, he was named the SEC Newcomer of the Year and recipient of the Conerly Trophy.[14][15] In the first round of the playoffs against Tulane, Chambliss threw for 282 yards and combined for three total touchdowns in a win.[16] In the 2026 Sugar Bowl, he completed 30 passes for a season-high 362 yards and two touchdowns, leading Ole Miss to a 39–34 upset victory in a rematch against Georgia; he was named the game's offensive MVP for his efforts.[17]
In November 2025, Ole Miss filed a waiver request with the NCAA to allow Chambliss a sixth year of eligibility, as he did not play his sophomore season at Ferris State (2022) due to persistent respiratory issues. On January 9, 2026, the NCAA denied the request, ending his college eligibility.[18] Ole Miss filed an appeal with the NCAA. On January 16, lawyers representing Chambliss sued the NCAA in Mississippi state court, asking a judge for preliminary and permanent injunctions which would allow him to play an additional season.[19] On February 5, 2026, Chambliss' appeal was rejected again.[20] After another appeal, Chambliss' injunction was made successful on February 12, 2026, granting him a sixth year of eligibility in college.[21]
