The Packers flew Freddie Mitchell to Green Bay on Monday and he will work out for them today in the hopes he will be able to provide some much-needed help at receiver. Green Bay already has lost receivers Javon Walker (torn knee ligament) and Terrence Murphy (neck) for the season and found out Monday it will be without Robert Ferguson for two to four weeks with a strained lateral collateral ligament in his left knee. Ferguson was injured during Sunday?s 23-20 loss to the Minnesota Vikings.
