According to Baby, Manziel is considered a senior and will look to complete his degree in recreation, parks and tourism sciences.
Manziel spent three years at Texas A&M as a member of the football team before going to the NFL. He redshirted his freshman year, and over the next two seasons, he threw for a combined 7,820 yards, 63 touchdowns and 22 interceptions.
In 2012, he became the first freshman to win the Heisman Trophy, and in his two years as the starting quarterback for the Aggies, the team won 20 games, including victories in the Cotton Bowl and Chick-fil-A Bowl.
The fact the 23-year-old returned to college likely means he has given up hope of signing with an NFL team this season. The Cleveland Browns released him in March, and he has yet to find another home in the league.
In June, Manziel's attorney, Jim Darnell, said his client was hoping to rejoin the NFL at some point during the 2016 season, per ESPN.com's Jeremy Fowler. A second source told Fowler a 2017 return is far more likely.
Should a team sign Manziel, he'll sit out four games following a violation of the league's substance abuse policy.
