"Due to NCAA rules I would have been ineligible," Sewell told JCFootball.com about why he isn't at Cal. "You can only transfer over nine summer credits immediately before you transfer and I would have been transferring over 12 credits, so I wasn't going to be eligible and Cal wanted me for this season, so they decided to move on."
With his option to play Pac 12 football gone, at least for this season, Sewell decided to commit to the other FBS program that extended him an offer -- North Texas.
""I just committed to North Texas," Sewell said. "It's a program that is on the rise and is going to shut a lot of the doubters up this year. The coaches have stuck with me and made me feel like family and we're going to continue building on that relationship.
"My close friend EJ (Ejiya) is apart of the team also and I just want to be able to come in compete and contribute to the team.
"With my commitment I don't have to worry about recruiting right now so I can just focus on my LA Valley team this year and continue to lead my team to another successful season."
Another thing that has Sewell excited is how happy the coaches were when he pledged his commitment to them.
"Super excited which is why I love coach (Mike Ekler) he's a passionate guy and you can tell he truly cares," Sewell noted. "He hasn't given up on recruiting me and he's been sticking with me throughout the process, so he was excited."
In addition to his offer from the Mean Green, Sewell also had offers from Southern, Prairie View A&M and Indiana State and while he's committed, he did say he fully intends to take all five of his official visits.
Sewell had a solid freshman season for the Monarchs last fall, totaling a team-leading 42 tackles to go along with 2.5 tackles-for-loss, two fumble recoveries, two interceptions and three pass breakups while helping to lead his team to a 9-2 record.
Sewell plans to finish up his academic work in December and he will have three years to play two following the 2016 football season.
