SANTA CLARA, Calif. – The San Francisco 49ers expect to get tight end George Kittle back this week for a key game against Green Bay but are unsure if top pass rusher Nick Bosa will be able to play.

The 49ers (5-5) finished last week’s 20-17 loss to the Seattle Seahawks without either Kittle or Bosa playing, leading to their third loss this season after blowing a late lead and leaving San Francisco’s playoff hopes in jeopardy.

Kittle missed the entire game with a hamstring injury but was back at practice on a limited basis Wednesday and said there was no doubt he would play Sunday against the Packers.

With Kittle out, the Niners matched their season low in scoring and were held to their fewest yards (277) since Week 6 last season at Cleveland.

Bosa left the game in the third quarter with a left hip and oblique injury. He was already dealing with a similar right side injury which he described as the most pain he has tried to play though. Bosa said Wednesday that the left side is still worse but that he is making progress, leaving open the possibility that he could play Sunday.

“It’s getting better every day,” he said. “We’ll see. Definitely a little early to call anyway, so we’ll find out. We’ve got a few days.”

Bosa’s absence played a big role in San Francisco’s recent blown lead after squandering games already against the Rams in Week 3 and the Cardinals in Week 5.

Seattle averaged 3.6 yards per play with six scores on five drives when Bosa was hurt. The Seahawks then averaged 6.3 yards per play the rest of the game with two TDs on their final three drives.

The loss to the Seahawks left the 49ers in a three-way tie for second place in the NFC West, one game behind first-place Arizona, and with little margin for error if they want to get back to the playoffs after losing the Super Bowl last season.

“Obviously you don’t want to be down feeling sorry for yourself, but obviously you don’t want to act like nothing’s wrong,” Bosa said. “I think we understand the task at hand, and we understand that we have to finish games. We’ve come very close in most of our losses and we’re probably three or four games away from being an 8-2 team, which is easy to say, but it just shows that if we could play better football throughout the game then we are as good as anyone and we believe that.”

In other injury news, quarterback Brock Purdy was limited in practice after injuring his right shoulder in Sunday’s game and did not throw any passes during the open portion of practice. But coach Kyle Shanahan said he expected Purdy to be able to play Sunday.

Running back Christian McCaffrey did not practice Wednesday to give some rest to his tendinitis that sidelined him for the first eight games this season.

Star left tackle Trent Williams also got a day off as he deals with an ankle injury that kept him out of practice all of last week.

NOTES: LB Tatum Bethune (knee) and DT Kevin Givens (groin) also did not practice Wednesday. … CB Charvarius Ward was limited in his first practice since the Oct. 28 death of his 1-year-old daughter. Shanahan said he would wait until later this week to determine whether Ward would be able to play. … WR Jacob Cowing (concussion protocol) and OL Jon Feliciano (knee) were also limited. … San Francisco signed DL Jonathan Garvin to the practice squad.
