Jeffery suffered a knee injury on Monday Night Football against the San Francisco 49ers. He had to have arthroscopic knee surgery on Wednesday, but his season may not be over. He will, however, miss Sunday's game after not practicing all week.
Fantasy Impact: Alshon Jeffery managed to have some fantasy impact early on this season before injuries derailed his rookie year. However, he's been banged up, and Jay Cutler has also missed some time with a concussion, decreasing the value of the Bears' passing attack.
Jeffery isn't worth keeping on your roster unless it is a deep league, keeper league or dynasty league.
