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).
