Williams expected to escape further punishment

LOS ANGELES -- USC Trojans freshman defensive tackle Leonard Williams has not been suspended by the Pac-12 for the punch he threw against Colorado that earned him an ejection, and it appears unlikely he'll receive any punishment from the conference office.

Trojans coach Lane Kiffin said after Tuesday's practice that he wasn't "allowed" to address Williams' situation.

"I think that's confidential," Kiffin said.

Previously, Kiffin had said he expected to hear back from the conference office Monday about a possible punishment for Williams. USC had not heard anything as of Tuesday afternoon, a school spokesperson said.

No news is typically good news as far as suspensions go, although there remains the possibility that Williams could be suspended for all or part of Saturday's game at Arizona.

"There's no set time on when the conference would announce any public reprimands or suspensions," Pac-12 spokesperson Dave Hirsch wrote in an e-mail Monday afternoon.

But each of the last two USC-related Pac-12 reprimands or suspensions were announced on a Monday or Tuesday.

Safety T.J. McDonald was suspended on a Monday for a half after the loss to Stanford last year. Quarterback Matt Barkley was publicly reprimanded on a Tuesday for comments made the previous week about Vontaze Burfict leading up to the Trojans' eventual loss to Arizona State.

Williams is expected to start at defensive tackle for the Trojans in Tucson this weekend. He told teammates that he punched a Colorado player in the facemask because he was first spit on in a second-quarter pile-up.
