Marcus Spears and Jeff Saturday disagree about whether the Bears or 49ers need a win on Sunday more. The Bears added wide receivers DJ Moore and Olamide Zaccheaus to the injury report Sunday morning with an illness and designated both as questionable. Right tackle Darnell Wright was added to the injury report Saturday with an illness and did not travel with the team. Five other players were affected by an illness this week, including backup nickel corner Nick McCloud, who was ruled out Friday. Both returner Devin Duvernay and linebacker D'Marco Jackson dealt with an illness that kept them out of practice until Friday.
