The best case scenario is he only needs a scope. The worst case scenario is that they have to do a regular operation, and cut him open.
If it's just a scope, Pennington should be ready for the start of training camp. If he has full-fledged shoulder operation, he might miss the beginning of training camp.
If Pennington has the more serious operation, the Jets will likely enter training camp with Brooks Bollinger, Ricky Ray and a veteran free agent in camp as their quarterbacks. It's a long shot, at this point, that Quincy Carter will be back with the team this year. He left the team during the playoffs to attend to a family matter, and never returned.
Jets team doctor Elliott Pellman will answer questions at a Tuesday press conference about Pennington's injury, and the prognosis.
