Fulton appeared in three games as a freshman, making two tackles. Following the season, Fulton was suspended by the NCAA for two seasons after he tampered with a drug test for performance enhancing drugs on February 2, 2017.[6] He appealed the decision, arguing that he believed that the test was for recreational narcotics, but the initial appeal was denied in March 2017. Fulton sat out the entirety of the 2017 season, but remained with the team and participated in daily practices.[7] Fulton then filed a second appeal after hiring an attorney arguing that proper drug testing protocol was not followed.[8] The second appeal was also originally denied by a panel of NCAA officials on August 9, 2018, but the decision was overturned on August 23.[9][10]
