GREEN BAY, WI (WHBL) - It’s been another rough training camp for the Green Bay Packers. Ten players were hurt during the team’s first nine practices, including three starters on offense. On Tuesday, we learned that receiver Jordy Nelson would miss the rest of camp after having a surgical procedure on one of his knees. Team officials did not specify the exact problem. General Manager Ted Thompson said the operation cleaned up a lingering injury. NFL.com said it was a minor problem that Nelson had been dealing with since playing in college. Coach Mike McCarthy said the goal is to have Nelson ready for the regular season opener on September eighth at San Francisco. Also, receiver and kick returner Randall Cobb appeared to hurt a shoulder during Tuesday's practice. Again, McCarthy did not say exactly what the problem was. The third starter, left tackle Bryan Bulaga, is apparently out for the year with a torn A-C-L. McCarthy says he won’t make that judgement until Bulaga’s second opinion comes in. A number of back-ups have also been hurt – including running back Alex Green, tight ends Ryan Taylor and Andrew Quarless. Rookie wide-outs Charles Johnson and Kevin Dorsey were hurt on the same day.
