Combs was arrested at about 12:30 p.m. at the Acosta Athletic Training Complex on campus for assault with a deadly weapon. No one was seriously injured.
Shortly before noon, Combs posted a photo on his Facebook page about a father-son football game. Combs' son Justin Combs is a defensive back for UCLA's football team.
He was taken to campus jail and was expected to be transported to the Los Angeles County Sheriff's Department Inmate Reception Center Monday night.
"I'm thankful that our staff showed the level of professionalism that they did in handling this situation. This is an unfortunate incident for all parties involved. While UCPD continues to review this matter, we will let the legal process run its course and refrain from further comment at this time," UCLA football coach Jim Mora said in a statement.
