Trojans coach Clay Helton announced Monday that Masina would miss the team’s opener against Alabama for a violation of team rules.
Cottonwood Heights, Utah police confirmed that there are two active investigations and that they are working with the Los Angeles Police Department on the matter. An attorney for Masina also confirmed the investigations.
The Utah incident happened in July, and the California one prior to that.
"USC is aware of the investigation involving student-athlete Osa Masina," the school said in a statement. "USC is cooperating fully with authorities in Utah, the lead agency in the investigation. Due to privacy laws and to protect the rights of our students, we are not able to discuss this matter further."
Masina, entering his sophomore season, made 25 tackles in 12 games last season.
