Smith (concussion) didn't participate in practice Wednesday, Cam Inman of the Bay Area News Group reports.

EDGE Analysis

The 49ers are merely playing the waiting game with Smith, who hasn't stepped on the practice field since sustaining a concussion in Week 14. Until he makes an appearance, a return date is nearly impossible to peg down due to the murky nature of such injuries. With the loss of Quinton Patton (foot) for the season, the 49ers' receiving corps has nary a reliable option among its healthy bodies, including Jeremy Kerley, Rod Streater, Aaron Burbridge, and Chris Harper.

Smith (concussion) has been ruled out of Sunday's game against the Falcons, The Sacramento Bee's Matt Barrows reports.

EDGE Analysis

Smith took a hard hit to the head during last Sunday's loss to the Jets, which kept him out of practice this week. The wideout will remain sidelined Sunday, leaving the 49ers without the top receiver on their depth chart.

Smith (concussion) missed Wednesday's practice.

EDGE Analysis

Smith's progress through the concussion protocol will determine his activity level on a daily basis. There's no telling when non-contact work will become a part of his regimen, but his head injury may be on the serious side after he was carted from the field Sunday versus the Jets. Expect some clarification on his status as the week continues.

Smith (concussion) did not take part in Tuesday's practice, Cam Inman of the Bay Area News Group reports.

EDGE Analysis

While Smith is seemingly still dealing with symptoms of the concussion he suffered Sunday, he was at least able to attend Tuesday's practice and observe from the side. If not before, the 49ers will provide an official update on Smith's health heading into Week 15 following their first official practice session of the week Wednesday.

Smith won't return to Sunday's outing against the Jets due to a concussion.

EDGE Analysis

Smith remained on the turf after coming down on his head and shoulder during an attempted catch. Carted off the field thereafter, his return to game action will now be subject to the concussion protocol. With Vance McDonald also leaving Sunday with a shoulder injury, the 49ers' remaining top receiving options are Jeremy Kerley and Quinton Patton.

Smith was held catchless in Sunday's loss to the Bears. He was targeted twice.

EDGE Analysis

The 49ers' passing game was nonexistent Sunday, netting just six yards in snowy conditions at Soldier Field. Smith was already a boom-or-bust play, and the weather ensured a dismal performance. Next week's matchup against the Jets' lackluster offense will likely have a low over/under, making Smith a riskier play than usual.

Smith (shoulder) corralled three of seven targets for 24 yards and a touchdown in Sunday's 31-24 loss to the Dolphins.

EDGE Analysis

The veteran speedster equaled his second-highest amount of targets on the season while getting into the end zone for the first time since Week 6. The three catches also matched a season high for Smith, who's had little chance to showcase his trademark deep speed with the Niners' relative inefficiency behind center. He'll look to maintain the positive momentum when San Francisco travels to the Windy City for a Week 13 road tilt against the Bears.

Smith (shoulder) is active for Sunday's game in Miami, Cam Inman of the Bay Area News Group reports.

EDGE Analysis

After testing out his balky shoulder in warmups, Smith will end his DNP streak at one contest. He'll attempt to make inroads against a Dolphins defense that has allowed 12.8 YPC and 10 touchdowns to wideouts in 10 games this season.

Smith is expected to play Sunday against the Dolphins, but he will test out his injured shoulder in pregame warmups, according to Ian Rapoport of NFL Network.

EDGE Analysis

Smith continues to be limited in practice because of the injury, and he is officially listed as questionable because of it, but he's apparently heading in the right direction, giving quarterback Colin Kaepernick a key piece of his arsenal.

Smith (shoulder) is listed as questionable for Sunday's game at Miami, Cam Inman of the Bay Area News Group reports.

EDGE Analysis

Smith has yet to log a full practice as his right shoulder heals, placing a cloud over his potential to play in Week 12. If he's sidelined for the second consecutive week -- and second time overall in his six-year career -- Colin Kaepernick won't have many reliable targets outside of Vance McDonald in the passing attack.
