The 49ers have activated S Talanoa Hufanga from IR. He put in limited practices all week and is officially questionable. But Jennifer Lee Chan of NBC Sports Bay Area on Friday called him "set to return" for Sunday's game against the Bears.

The 49ers left S Talanoa Hufanga off the final Week 3 injury report for the first time this season. That should mean the first action for Hufanga since he suffered an ACL tear in Week 11 last season. I wouldn't bet on the safety getting a full workload, and there's likely more risk than reward to playing Hufanga in IDP lineups. But we'll see how quickly he can ramp back up to full duty. Expect Hufanga to reclaim the position that George Odum and Malik Mustapha have covered the first two weeks.

Niners HC Kyle Shanahan said after Sunday's game that S Talanoa Hufanga "most likely" suffered an ACL tear in Sunday's win over the Buccaneers. That would obviously end Hufanga's season. Rookie Ji'ayir Brown filled in after Hufanga left and figures to start going forward

Niners S Talanoa Hufanga (concussion) and CB Charvarius Ward (groin) are questionable for Sunday's game against the Chiefs. DL Arik Armstead (foot, ankle) has been ruled out. It'll be the 3rd straight game he has missed.

Niners EDGE Nick Bosa is off the injury report and ready to play Sunday's game against the Chiefs. S Talanoa Hufanga (concussion) is questionable. He managed just a single limited practice and seems unlikely to play. CB Charvarius Ward (groin) is questionable as well. The 49ers have ruled DL Arik Armstead (foot, ankle) out.

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.
