"I'd like to thank Joel for everything he's done for TCU and his commitment to our program," TCU head coach Gary Patterson said. "Joel is very close to completing his second degree at TCU, and he decided it was time to move on from football. We will miss him and wish him the best."
Hasley has already received his communication studies degree and will complete a second degree in geology later this year.
Note: Hasley played prep football at Aledo High School, anchoring the Bearcats' defense on state championship teams.
