The school released a short statement on Thursday explaining that Reese left for "personal reasons." The junior safety did not elaborate on the reasons for his exit, but took to Twitter to thank his coaches and fans for the experience with the Cowboys.
"I'm very thankful to the coaches that have helped me along this journey," Reese said via his Twitter account. "First off, I would like to thank God for the opportunity to attend the Univ. of Wyoming. I also would like to say I'm very proud to have played with a great group of young men and even better friends. I also want to thank my coaches for allowing me to grow and aiding in my maturation process. I wish my teammates and brothers the best of luck this weekend and in the future."
Reese was listed as the starting strong safety for Saturday's game. His backup on the depth chart is freshman Xavier Lewis.
Wyoming (4-6, 2-4 Mountain West) needs to win its final two games to become bowl eligible. The Cowboys host Hawaii this week then travel to Utah State next Saturday for the regular season finale.
