According to a statement from the Ducks, Bell was cited after he interfered with a university parking officer who was attempting to place a parking citation on his vehicle.
"I want to apologize for my actions," Bell said in the statement. "I did not react properly to the parking citation and I am disappointed in my conduct. I have already apologized personally to the Parking Officer and want to also make a public apology. Representing the University of Oregon is a privilege and I will do better to live up to those standards."
Oregon won Sunday night's game 92-75 over Washington State.
Bell, a four-star recruit out of high school from Long Beach, Calif., entered Sunday as Oregon's leading rebounder at 7.0 per game and shot-blocker at 3.1 per game. The 6-foot-8 Bell is also averaging 5.7 points in 24.5 minutes per game.
Oregon (17-7) is tied for third in the Pac-12 with a 7-4 conference record. The Ducks next play Wednesday at USC.
