SANTA CLARA -- Tarvarius Moore is in the NFL’s concussion protocol after the 49ers' backup safety and special-teams player injured his head in the fourth quarter of the 49ers’ 34-31 win over the Los Angeles Rams on Saturday night.

Moore was injured while making a big hit on Rams punt returner Nsimba Webster early in the fourth quarter of the 49ers’ victory at Levi’s Stadium.

Webster fielded Mitch Wishnowsky’s punt on one bounce and Moore, running at full speed from his spot as the gunner on the left side, immediately hit Webster after a 1-yard return.

Moore was evaluated for a concussion, and he now goes into the concussion protocol. He will not be eligible to play in the 49ers’ regular-season finale against the Seattle Seahawks until he clears the necessary steps in order to return to play.

Moore started the 49ers' first three games of the season at free safety in place of Jimmie Ward. He has turned into one of the team's best special-teams performers, and Moore had one of the plays of the season in the team's victory over the New Orleans Saints.

The 23-year-old is one of four players with injury concerns as the 49ers head into the important Week 17 game, which will decide the NFC West champion. If the 49ers win, they will earn home-field advantage in the NFC playoffs. A Seahawks victory would drop the 49ers to the No. 5 seed, and they would open the playoffs with an opening-weekend game at the winner of the NFC East.

Defensive end Dee Ford is not expected to be available for Sunday’s game due to hamstring and quadriceps injuries. But the club expects Ford to be available for the playoffs, a source told NBC Sports Bay Area.

Safety Jaquiski Tartt (ribs) and defensive tackle Julian Taylor (elbow) have missed multiple games with their injuries. Each player is considered day-today. The statuses of both players will be determined later in the week.
