The San Francisco 49ers already have ruled out two defensive linemen but are hopeful Nick Bosa will be available on Sunday at Atlanta.

Head coach Kyle Shanahan confirmed on KNBR Thursday night that defensive tackle Javon Kinlaw will not play in the Week 6 contest due to a knee injury. Defensive tackle Arik Armstead already was ruled out with foot and ankle injuries.

Bosa did not practice Wednesday or Thursday with a groin injury, but Shanahan sounded optimistic about having him on the field when the 49ers (3-2) face the Falcons (2-3).

“We’re not going to have Kinlaw or Armstead. And I’m still really hoping to get Bosa for Sunday,” Shanahan said. “He usually ends up being good, but he wasn’t able to (practice Thursday). Hopefully, he’ll be good by (Friday). Regardless, I just hope he’s good by Sunday.”

Bosa shares the NFL lead with six sacks through five games, to go along with 15 tackles and 16 quarterback hits.

Bosa, who turns 25 on Oct. 23, has 30 1/2 sacks in 40 games (38 starts) since the 49ers drafted him with the No. 2 overall pick in 2019.
