Under the new rule, backpacks and hard-sided bags are now banned from all NBA games, according to a representative for the Chicago Bulls. Bags larger than 14" by 14" by 16," such as diaper bags, purses and briefcases, are also prohibited, Bulls representatives said.
Single-compartment string backpacks and backpack-shaped purses are still permitted, officials said.
Bulls representatives said that Bulls fans are discouraged from bringing bags to the United Center, as all bags are subject to inspection.
