San Francisco 49ers safety Talanoa Hufanga sustained a right knee injury against the Tampa Bay Buccaneers that could keep him out well beyond Sunday's game.

Hufanga will have further tests on the knee on Monday morning, but coach Kyle Shanahan indicated after the Niners' 27-14 win that the organization is bracing for an ACL injury that could mean the end of Hufanga's 2023 season.

"We'll find out tomorrow on that," Shanahan said. "We don't know for sure. Most likely it's ACL but can't confirm it so we'll find out later."
