Johnson was injured early in the Packers' 25-13 win over Seattle last week. He returned to the game, but didn't practice this week until Friday.
Johnson said he'll be ready to go come game time.
"It's like any other injury," Johnson said. "You might not make it through the week, but you just have to be ready for Sunday, that's all."
In other injury news, DE-DT Aaron Kampman could play after sitting out three games with a sprained ankle. He participated in limited practices Thursday and Friday.
Safety Antuan Edwards also returned to practice, with mixed results.
"I wanted to see if I could move around," Edwards said.
Edwards did not work out with the first-team defense in his first practice since injuring his ankle in the team's Sept. 29 win over the Bears.
Marques Anderson is expected to make his second consecutive start in place of Edwards when the Packers take on the Chiefs.
