GREEN BAY, WI (WHBL) - Green Bay Packers’ defensive linemen Ryan Pickett and Mike Daniels are both listed as day to day, in the wake of the injuries they suffered Tuesday at training camp. Pickett bruised one of his knees, and Daniels had knee and groin injuries. After practice this morning, coach Mike McCarthy said offensive lineman Derek Sherrod will not return to practice this week. The coach said the second-year pro is doing all he can to recover from a broken leg suffered last year, and a setback this spring. NFL Commissioner Roger Goodell visited today’s practice, along with some replacement officials taking the place of the regulars, who don’t have a contract. McCarthy said there is not a concern about the replacements - at least at the moment – and he was planning to meet with them later today. Also, former Packers general manager Ron Wolf and former coach and T-V commentator John Madden showed up at today’s practice.
