Montgomery only attended
LSU for one semester before returning home due to academic issues and his mother falling ill. He said that, after returning home, "one day me and my brother, we was in the backyard and we were throwing the football. He was like, 'Look, bro, you could really do this.'" He then briefly enrolled at the
University of Houston to walk-on with the
Houston Cougars, but was unsuccessful due to the
COVID-19 pandemic. He broke the school records for single-season catches, receiving yards and receiving touchdowns. He was the only Division III player at both games and became the first John Carroll player ever to be invited to the Senior Bowl. ==Professional career==
