The San Francisco 49ers got several players back from injuries on Monday night but weren't able to escape the overtime loss to the Seattle Seahawks without other issues emerging.

Head coach Kyle Shanahan jumped on a conference call with reporters today and shared the following injury updates.

As reported here, defensive end Ronald Blair did indeed suffer a torn ACL in his right leg, will have season-ending surgery, and be placed on injured reserve.

Left tackle Joe Staley, whose game on Monday was his first back from a fractured fibula, suffered a fractured finger against the Seahawks (reported here). He may require surgery, which would force the veteran offensive lineman to miss a "couple of weeks," said Shanahan.

Staley is seeking a second opinion.

Wide receiver Emmanuel Sanders is day-to-day with a rib injury (reported here) and could be a game-time decision against the Arizona Cardinals. The setback doesn't sound like a long-term concern.

Matt Breida aggravated his ankle, and is day-to-day. Shanahan said the team will see how the running back feels headed into practice on Wednesday.

Defensive tackle D.J. Jones suffered a groin injury.

"We haven't gotten his scan back yet, but he's expected to miss at least a week," Shanahan said.

Those were the new injuries. The 49ers also had some existing injuries headed into Week 10.

"Existing injuries, [Robbie Gould] and [George Kittle] are still in the same boat," Shanahan said. "I'm hopeful for them this week but still pretty similar to last week.

"And then [Ahkello Witherspoon], he's day-to-day but expecting him to practice tomorrow, so we'll see how he is when he gets in."
