Carey (concussion) is active for Sunday's game against the 49ers, Rich Campbell of the Chicago Tribune reports.
Meanwhile, fellow backup running back Antone Smith is inactive, meaning Carey will be third string behind Matt Forte and Jeremy Langford for Sunday's game. Carey, who missed last Thursday's matchup with the Packers due to the concussion, is set to notice a decline in touches with Forte now back to full health. While working in a complementary role behind Langford in his last three games, Carey had amassed 116 yards on 30 carries.
