I saw this coming for a while. He's going to Duke to pursue a masters degree. Good luck young man!

MOD EDIT - Detail pulled from Bucknuts writeup: 

"Bucknuts can confirm that fourth-year junior offensive lineman Evan Lisle will be leaving the program as a graduate transfer.

Multiple sources have confirmed to Bucknuts that Lisle's destination will be to Duke, where the Centerville (OH) product will use his last year of eligibility and pursue a Master's Degree."
