(670 The Score) Bears receiver Allen Robinson took a positive step toward full strength Thursday when he worked as a full participant in practice.
Robinson has played the last two games with a nagging ankle injury, which he suffered in a win on Oct. 10. Thursday marked the first time that Robinson had practiced in full since suffering the injury.

In other injury news, Bears pass rusher Khalil Mack (foot) didn't practice once again. Defensive lineman Akiem Hicks (groin) and safety Tashaun Gipson (hip) were limited participants. Returner Jakeem Grant (ankle) was also a full participant after being limited previously.
The Bears (3-4) and 49ers (2-4) kick off Sunday at noon CT from Soldier Field.
