Stewart attended Vero Beach High School, where as a senior he made 95 tackles (13 for loss) and 7 sacks, while receiving All-state honors. He was invited to play in the Georgia/Florida High School All-Star Game. He also practiced the shot put and discus throw.

He accepted a football scholarship from the University of Southern Mississippi. As a freshman, he appeared in 8 games as a reserve defensive lineman. The next year he was limited with an ankle injury and made 26 tackles.

As a junior, he began the season as the backup to John Nix, until being moved into the starting lineup in the third game against the University of Nebraska, after Nix suffered a toe injury during the first games. He would end up being a key player, posting 47 tackles (11 for loss), while helping his team win the Conference USA championship with a 9–3 record and a 23–17 win over Colorado State University in the 1999 Liberty Bowl.
