There is concern within the Giants organization that Jason Pierre-Paul could miss training camp and the start of the season due to his injured hand. The Giants have already pulled their long-term offer to Pierre-Paul after news of the hand injury.
The Giants are still awaiting medical information about Pierre-Paul's hand, but the signs indicate it is a severe injury. He is believed to have suffered nerve damage within his hand. This would be a big blow to the Giants pass rush as Pierre-Paul led the team in sacks last season.
