Jones is the No. 8-ranked defensive tackle and No. 61-ranked player in the class of 2016, according to the recruiting website Rivals.com.
Jones said his relationship with the Rebels' coaching staff was a "major" factor in his decision to switch to Ole Miss.
"The players and coaches treat you like family," he said. "I love coach (Chris) Kiffin... and most of all coach (Hugh) Freeze."
Earlier this month, Jones talked about how his recruitment unexpectedly "took off" after his original commitment to Alabama.
"I thought the pressure would stop with all the 'when are you going to commit, where are you going to commit' talk," Jones said. "But when I did commit to Alabama, it started worsening."
The 6-foot, 280-pound Jones has drawn scholarship offers from Florida State, Georgia and Mississippi State, among other programs. Jones is the first defensive lineman and fifth player in the class of 2016 to verbally commit to Ole Miss.
The Rebels open the season Aug. 28 against Boise State.
