San Francisco 49ers star edge rusher Nick Bosa was added to Thursday's injury report and did not participate due to a calf issue. Bosa previously managed a knee injury coming off his season-ending knee surgery. Head coach Kyle Shanahan is expected to provide further updates on Friday as the team takes a cautious approach with their premier defensive player ahead of Sunday's game against the Cardinals.
