SANTA CLARA – Quarterback Colin Kaepernick was added to the 49ers’ injury report on Thursday, though he took part in full participation, with a back condition.
The 49ers did not disclose the exact nature of Kaepernick’s injury, but it is not expected to have any impact on his status for Sunday’s game against the Arizona Cardinals. Kaepernick was not listed on the 49ers’ injury report on Wednesday.

Tight ends Vernon Davis (ankle, knee) and Vance McDonald (knee) remain questionable for Sunday’s game. Cornerback Tramaine Brock and right tackle Anthony Davis (hamstring) are not expected to play.
Meanwhile, Cardinals quarterback Carson Palmer took part in limited practice due to a nerve injury in his throwing shoulder. Backup Drew Stanton appears to be in line to make his second consecutive start.
