Niners LB Fred Warner fractured and dislocated his right ankle in Sunday's loss to the Buccaneers, HC Kyle Shanahan announced after the game. He'll have surgery and miss the rest of the season.

Niners LB Fred Warner is expected to play through his ankle sprain today against the Cardinals, according to multiple reports. There might still be some risk of limited playing time, but this early report indicates that he's better than a game-time decision. He appeared to be moving well in his Friday return to practice. I moved Warner back up the Week 5 LB rankings on this morning's news. He'll obviously carry some re-injury risk -- but also plenty of fantasy upside. Weigh both vs. your other IDP lineup options.

San Francisco 49ers DE Nick Bosa is officially questionable for Saturday night's game against the Packers after suffering a concussion in the Wild Card win at Dallas. HC Kyle Shanahan said Thursday, though, that Bosa's chances of playing are "looking good," according to ESPN's Nick Wagoner. LB Fred Warner, meanwhile, carries no injury status into Saturday's game after hurting an ankle against the Cowboys.

The 49ers deemed LB Fred Warner (hamstring) doubtful for Sunday's game at Seattle. The only surprise there is that he has any chance of playing. Initial reports projected him to miss a week or 2 with the injury. Expect the Niners to be without their star LB, though. LB Dre Greenlaw (groin) has been ruled out. LB/S Marcell Harris (concussion) is questionable. The depleted LB corps helps the outlook for Seahawks TE Gerald Everett.

Niners LB Fred Warner left Sunday's game against the Vikings with a hamstring injury. Keiana Martin of the team website reports that Warner will have an MRI on Monday.
