Niners S Talanoa Hufanga entered the concussion protocol Monday. HC Kyle Shanahan said Hufanga passed his concussion test during Sunday's loss to the Falcons, and then another after the game, according to 49ers Webzone. But he then had concussion symptoms Monday morning, and a 3rd test placed him in the protocol. Plan on not having Hufanga available for IDP lineups this week. We'll keep an eye on his status.
