Joe Staley, Torrey Smith miss 49ers' Wednesday practice

SANTA CLARA, Calif. -- The San Francisco 49ers have been forced to make a series of roster moves in recent days because of season-ending injuries to tight end Vance McDonald (shoulder) and center Daniel Kilgore (hamstring).

But the Niners have two more key players they're still evaluating and hoping to get back who again did not participate in Wednesday's practice. Left tackle Joe Staley (hamstring) and receiver Torrey Smith (concussion) have both lost impressive consecutive starts streaks this season and could be out again Sunday against the Atlanta Falcons depending on how the rest of the week goes.

Staley's streak of 92 consecutive regular-season starts ended last week against the Jets after he was a late add to the injury report and was unable to play. Smith played in that game but suffered a concussion when he landed awkwardly after attempting to make a contested catch. He remains in the concussion protocol and would have to be cleared before he can play again.

During the portion of practice open to the media, Staley worked on the side with the training staff while Smith observed in sweats.

Niners coach Chip Kelly also updated Kilgore's injury, which he'd initially said was a knee ailment. Kilgore actually suffered a torn hamstring and required surgery.

Here's the 49ers complete Wednesday injury report:

Did not participate -- OT Joe Staley (hamstring), WR Torrey Smith (concussion).

Limited participation -- WR Aaron Burbridge (hamstring), DT Glenn Dorsey (knee).

Full participation -- DT Quinton Dial (elbow), RB Shaun Draughn (ribs), LB Eli Harold (toe), LB Aaron Lynch (ankle).
