Christian Kirk Placed on Injured Reserve with Meniscus Injury

San Francisco 49ers wide receiver Christian Kirk has been placed on injured reserve after sustaining a meniscus injury during practice. Kirk was ruled out for Week 9 before being moved to IR, adding to a severely depleted San Francisco receiver corps that is also missing Mike Evans and Deebo Samuel. The injury prompted the 49ers to trade for veteran wideout Keenan Allen from the Indianapolis Colts ahead of the trade deadline.
