The 6-foot-4, 215-pounder from Rochester, Ill., started five games for the Cowboys as a true freshman in 2012 and was OSU's first true freshman opening-day starter at quarterback since at least 1950. Despite an injury-riddled season, he still finished with 81 completions in 131 attempts for 1,108 yards with six touchdowns and seven interceptions.
"This was not a decision I took lightly, but it is a decision that I felt was right for me," Lunt said in the release. "I would like to express my sincerest gratitude to the entire Oklahoma State University community. Specifically, I would like to thank the coaches, players, and the whole OSU football family. I wish the Cowboys the best of luck in the future."
Lunt said he has not made a decision to where he will transfer.
Lunt's decision leaves fifth-year senior Clint Chelf and sophomore J.W. Walsh, who each started games in 2012 and battled throughout the spring, as the top candidates to start when OSU opens the season against Mississippi State on Aug. 31 in the Texas Kickoff Classic at Reliant Stadium in Houston.
