Amukamara missed the Bears' win over the Cowboys last Thursday due to the injury, but the team is hopeful he can return at the Green Bay Packers on Sunday.
Bears right tackle Bobby Massie didn't practice Wednesday and is in jeopardy of missing his fourth consecutive game. Massie suffered an ankle injury in Chicago's loss in Los Angeles on Nov. 17.
Linebacker Danny Trevathan (elbow), tight end Ben Braunecker (concussion), receiver Taylor Gabriel (concussion), defensive lineman Roy Robertson-Harris (foot) and receiver Javon Wims (knee) also didn't practice.
Bears defensive tackle Akiem Hicks practiced again Wednesday, as expected. He missed the past eight games with an elbow injury and is eligible to return from injured reserve this Sunday. The Bears have until 3 p.m. Saturday to activate him.
Kickoff between the Bears (7-6) and Packers (10-3) comes at noon Sunday from Lambeau Field.
