Brandon Marshall, Alshon Jeffery could miss San Francisco 49ers clash

The Chicago Bears could be without key players Brandon Marshall and Alshon Jeffery when they take on the San Francisco 49ers on Sunday.

The Bears will have to contend with a home 49ers crowd buoyed by the imminent unveiling of the new Levi's Stadium, with the added possibility of being without their star wide receivers.

Marshall was limited to a short stint in practice on Friday because of an ankle injury, with Jeffery also noticeably limited in the session, resulting in both players being listed as questionable for the encounter.

The Bears are also suffering injuries to Matt Slauson and Roberto Garza, while Josh Morgan is doubtful to play too.
