The Green Bay Packers will not have leading receiver Randall Cobb for multiple weeks but could have receiver James Jones back in time for Sunday's game against the Cleveland Browns. Packers coach Mike McCarthy would not reveal any details of the injuries but a source told ESPN NFL Insider Adam Schefter that Jones has a sprained posterior cruciate knee ligament. ESPN Senior NFL Analyst Chris Mortensen confirmed a report by the Milwaukee Journal Sentinel that said Cobb has a fractured fibula and could miss 6-8 weeks.
