FILE - In this Aug. 7, 2014, file photo, San Francisco 49ers quarterback Blaine Gabbert (2) looks for a receiver as he is pressured by Baltimore Ravens outside linebacker Elvis Dumervil (58) in the first half of an NFL preseason football game in Baltimore. A person with knowledge of the decision says quarterback Colin Kaepernick has been told he won't start Sunday, Nov. 8, 2015, for the San Francisco 49ers, replaced by backup Gabbert. The person spoke on condition of anonymity Monday, Nov. 2, 2015, because the decision wasn't to be discussed publicly. (AP Photo/Nick Wass, File)
