Florida
After the season, Del Rio transferred to the University of Florida.[6][7] According to a university spokesperson, Del Rio was granted an extra year of eligibility by the NCAA in 2015. The extra year made him a redshirt sophomore for the 2016 season.[8]
After sitting out 2015 due to transfer rules, Del Rio was named the starting quarterback for Florida in 2016.[9] In the third game of the year against North Texas, Del Rio suffered a knee injury on a blindside hit, which forced Del Rio to miss the next two games. He had also suffered an AC joint sprain in his throwing shoulder earlier in the North Texas game, which hampered his play when he returned from injury. Del Rio returned from injury to play against Missouri on October 15. A week later in a game against Georgia, he suffered a torn labrum in his non-throwing shoulder. After struggling in a 31–10 loss against Arkansas on November 5, Del Rio was finally shutdown for the season due to injuries. After undergoing surgery on both shoulders, he was sidelined for all of spring practice in 2017.[10][11]
Del Rio began the 2017 season behind starter Feleipe Franks and top backup Malik Zaire. With the offense struggling against Kentucky, Del Rio came off the bench and led the Gators to a comeback victory. As a result, Del Rio was named the starting quarterback the following week against Vanderbilt. In the second quarter, Del Rio suffered a broken collarbone and was ruled out for the rest of the season.[12] In November 2017, Del Rio announced that he would be forgoing his sixth and final year of eligibility.[13]
