"Chris Casher is being withheld pending review of an academic-related matter," the statement read. "Student privacy will not allow us to expand any further."
The 6-foot-4, 250-pound Casher, a redshirt sophomore, was slated to make his first career start after playing in 13 games last season. He missed most of his freshman season with a knee injury.
The Seminoles won the game, 37-31.
Casher missed practice Thursday, and Seminoles coach Jimbo Fisher said it was because Casher had a class-related absence.
During the summer, FSU had placed Casher on probation for one year for two violations of the university's student code of conduct stemming from the sexual assault investigation into quarterback Jameis Winston, the Wall Street Journal reported.
In 2012, police briefly detained Casher and Winston after a person reported two men were carrying a gun on campus, USA Today reported. It was a pellet gun, and Winston and Casher told police they were shooting at squirrels, according to the report.
The two were also investigated for damage at the apartment complex they lived at during their freshmen seasons. The damage from the BB gun "battle" cost $4,200, the report stated.
