The former University of Texas players are enrolled for the spring semester at the Austin campus, an official in the registrar's office confirmed Friday.
Young, who left for the NFL in January 2006 shortly after winning a national championship, has enrolled as a full-time student again. Griffin, the team's top draft pick last year, also has enrolled for the spring semester.
Young's marketing manager, Mike Mu, said finishing college and earning a degree have always been important to his client.
"He made a promise to his mother when he decided to leave school early, and he's about two semesters away," Mu said.
Young is in the process of changing his major to education and early child development, Mu said. Young is taking a full schedule of about 15 credit hours this semester and may be close enough to finish with a couple of online courses.
Coach Jeff Fisher fired Norm Chow on Jan. 15 and hired former coordinator Mike Heimerdinger to juice up an offense that managed only nine touchdowns passing in 2007.
The Titans start their offseason program March 24, with their on-field sessions tentatively scheduled between April and June. The spring semester at Texas wraps up May 13.
Griffin is majoring in youth and community studies.
Young has been in class for more than a week, and Mu said his schedule is flexible with no classes on Fridays. He is working with Griffin to stay in shape.
