On Sunday, the San Francisco 49ers won their fourth game in a row, but it did not come without a bit of controversy.

After the game, Minnesota Vikings head coach Mike Zimmer decided he would call out the 49ers defensive tactics during the postgame press conference.

“These guys hold all the time,” Zimmer said of San Francisco’s defensive backs. “They’re grabbing us around the waist, grabbing us on our backs. Officials don’t want to call it every play, but until they start calling it every play, they aren’t going to stop doing it.”
