Adams has not practiced all week because of his sprained left ankle -- an injury he originally sustained in Week 2 against the Seahawks and aggravated three plays into Monday night’s game against the Chiefs.
He was seen in a walking boot in the locker room this week, although he disputed reports that he had the dreaded high-ankle sprain.
Packers coach Mike McCarthy categorized Adams' chances of playing Sunday as “slight.”
“He’s going to have to jump around tomorrow, jump through some hoops,” McCarthy said Friday morning before the team was scheduled to fly to California. “We’ll see how it goes.”
The Packers, who are departing a day earlier than usual, have a practice scheduled Saturday in the San Jose area.
Safety Morgan Burnett, who did not play against the Chiefs because of a recurring calf injury, has a better chance to play than Adams.
“He’s getting better,” McCarthy said. “He’s definitely closer.”
The Packers will release their official injury designations (probable, questionable, doubtful or out) later on Friday.
