Other assistant coaches charged are Chuck Person of Auburn, Emanuel Richardson of Arizona and Lamont Evans of Oklahoma State.
The grand jury returned the indictments against eight of 10 men arrested in September.
When charges were first announced, USC Athletics tweeted a statement regarding the situation, saying the school has hired former FBI Director Louis J. Freeh and his firm, Freeh Group International Solutions, to conduct an internal investigation into the matter. The tweet also stated that Bland has been placed on immediate administrative leave.
