"We're aware of the situation, and internal discipline has been taken," he said. "That discipline will remain in-house."

The identity of the player is freshman defensive lineman Liam Jimmons, who is reportedly being investigated for assault, per The Spokesman.

"We are looking into it," WSU Police Assistant Chief Steve Hansen said. "We're still gathering information, talking to witnesses, reaching out to USC to see if we can interview or they'll interview the player for us. They'll send it over to the PA's office and see what they think. Earliest is going to be next week that we get this all combined."
