SANTA CLARA -- Wide receiver Torrey Smith sustained concussion in the third quarter Sunday and did not return to action.
Smith went up, along with New York Jets cornerback Juston Burris, on a deep pass from Colin Kaepernick. Smith jumped for the ball, which landed incomplete, and appeared to land on his head and shoulder area.
He remained motionless on the Levi’s Stadium turf for several seconds. After the team’s medical staff encircled him, Smith sat up after several moments. He was taken off the field on a cart and transported to the locker room area for further examination.
Smith, the 49ers’ nominee for the Walter Payton NFL Man of the Year award, appeared to be emotional as he left the field with a towel draped over his face. He now goes into the NFL’s concussion protocol, which he must pass in order to be cleared to return to action.
Smith did not catch a pass on Sunday. The deep ball was the only time in which he was targeted with a pass. He has 20 catches for 267 yards and three touchdowns on the season.
SANTA CLARA — The 49ers head into Sunday's game with a similar lineup as in last week's win over the Denver Broncos.
Nickel back K'Waun Williams will miss the game against the Seattle Seahawks at Levi's Stadium with a knee injury. His absence in a second consecutive game will open the door for rookie D.J. Reed to play another significant role in a game in which the 49ers likely will have five defensive backs in the game for most of the day against Seahawks quarterback Russell Wilson.
Matt Breida is active, but the staff likely will keep the running back on a pitch count in relation to how his ankle feels during warmups and throughout the game. Rookie Jeff Wilson’s performance over the past two weeks gives 49ers coaches no reason to push Breida any more than necessary. The team deactivated veteran Alfred Morris, so Matthew Dayes will be the No. 3 running back.
Marquise Goodwin is active, but 49ers coach Kyle Shanahan has been wanting to get rookie wide receiver Dante Pettis more playing time. Goodwin could be worked in slowly again, as he was last week, but the team needs to stretch the field against the Seahawks, and using him could be a way to gain an advantage.

Jaquiski Tartt will be out for his second game in a row and his sixth of the season. Marcell Harris will resume his spot at strong safety and try to help slow down the Seahawks' run game. He had a rough first game but did redeem himself in his second game against the Broncos.
Seahawks running back Rashaad Penny is out, so Harris will try to stop Chris Carson and former 49ers running back Mike Davis.
Sheldon Day is inactive for the second week in a row as the 49ers staff takes a closer look at nose tackle D.J. Jones in their evaluations for next season.

If you’re fortunate enough to still be in the fantasy football playoffs and are counting on 49ers and Seahawks players to perform, we have good news: Matt Breida, Marquise Goodwin and Dante Pettis, as well as Seattle wide receiver Doug Baldwin, are all set to play Sunday, per ESPN’s Adam Schefter.
Breida missed last week’s 49ers win over the Broncos because of an ankle injury. He’s been battling ankle issues all season long, but when healthy, he’s been the 49ers best running back. If Breida is limited at all, Jeff Wilson Jr. will take over the bulk of the carries.
Pettis has been on a tear lately, with four touchdowns in his last three games. The rookie had his career-best game when the 49ers played these same Seahawks two weeks ago (five receptions for 129 yards and two TDs).
Goodwin returned last week after a two-game absence due to personal reasons, but he has been dealing with a calf injury. Although Goodwin is back, 49ers coach Kyle Shanahan said the veteran receiver might lose snaps because of Pettis’ emergence.
For the visiting Seahawks, Baldwin is set to play after missing one game with a hip injury. Baldwin scored a touchdown against the 49ers when the two squared off Dec. 2, but he has fought injuries all season, and he didn’t play last week for Seattle.
