Jenkins, a three-year starter projected to be a first-round NFL draft pick, has eight career interceptions. He had three this past season, and was a first-team, All-SEC selection by The Associated Press. He missed the Outback Bowl following shoulder surgery.
Consideration of the recovery time following surgery possibly affecting his NFL draft preparations led Jenkins to reconsider turning pro, sources told ESPN's Joe Schad. Jenkins had told teammates and multiple former coaches that he would enter the draft.
Jenkins was rated as the No. 2 cornerback in the draft, and the No. 11 player overall, by ESPN draft expert Todd McShay.
"I spent some time with my family and coach [Will] Muschamp and came to the conclusion it was in my best interest to return to school," Jenkins said in a statement. "Coach Muschamp was very supportive throughout the whole process, regardless of my decision, but he wanted to make sure I had all of the facts. I'm looking forward to working towards my degree, completing my rehab and getting back on the field with my teammates."
Muschamp commended Jenkins for making a "mature decision."
"It would have been real easy for Janoris to make an emotional choice and leave early," Muschamp said. "But with our contacts in the NFL, we were able to assist him in understanding his draft status and he made an educated decision that will be beneficial to him in the long term."
