USC sophomore linebacker Osa Masina will miss the season-opener against Alabama for a violation of team rules. Though coach Clay Helton, who announced the suspension on Monday night, did not elaborate on the circumstances of the suspension, he did indicate that Masina will not travel with the team to Arlington, Texas, for the game.

According to ABC4 in Salt Lake City, Masina is under investigation for two different sexual assaults, one in Los Angeles and one in Cottonwood Heights, Utah. No charges have been filed against Masina, and he has not been arrested, but there is a search warrant has been issued in the Cottonwood Heights case.

The school has also admitted knowledge of the investigation in Utah.

USC is aware of the investigation involving student-athlete Osa Masina. 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 battled Michael Hutchings for starter’s reps at linebackers in spring ball and fall camp but was listed as a backup on the team’s depth chart for this week. The former five-star prospect from Utah had 25 tackles and a fumble return for a touchdown over 12 games as a freshman in 2015 and was one of several players expected to take a big step forward in 2016 under new defensive coordinator Clancy Pendergast.
