Thomson, whose injuries have caused him to miss stretches of the last two seasons, was awarded a rare two-year clock extension by the NCAA this offseason, essentially resetting him to junior status.
Saw this posted on our board a while back. Not sure the total year count, but yes he has 2 seasons left. Here is the Hornetsports release:
In a nearly unprecedented decision, the NCAA granted Thomson a two-year extension to his clock. The quarterback transferred to Sacramento State prior to the 2017 season which was believed to be his junior year. Instead, Thomson will take the field in 2019 as a junior and could play again in 2020.
