Others may be questioning Jets coach Rex Ryan for inserting Mark Sanchez at quarterback in the fourth quarter of a preseason game but Sanchez would not yesterday.

“I’m not here to second-guess the coaches” Sanchez said. “If they call you to play you better be ready to play and I was. So I warmed up went in played and tried to win.”

Giants defensive tackle Marvin Austin obliterated Sanchez’s right shoulder and now the Jets’ starting quarterback situation is murkier than ever. Ryan deflected questions about who will start the season his decision to put Sanchez in the game and even if rookie Geno Smith will play Thursday night against the Eagles.

What is clear is that Sanchez is hurting. While the Jets won’t divulge the extent of the injury a source said Sanchez’s status for the Sept. 8 opener with the Buccaneers is questionable at this point. The Jets are unsure of when Sanchez can attempt to throw again. He has been ruled out of practice today and out of Thursday’s game. Friday is the earliest he could practice.

A source would not say how bad Sanchez’s shoulder is but said the quarterback does not just have a bruised shoulder as has been reported. The bruising is a symptom of a more serious injury but how serious remains a mystery.

Sanchez played the part of a good employee yesterday as he did not divulge anything about the injury in a 10-minute session with reporters. He stood with his right hand in his pocket and never moved his arm.

“I’m obviously not happy that I’m hurt” Sanchez said. “I felt like I was putting together a good camp so it’s an unfortunate thing. But there’s no time to gripe about it. [I] just have to rehab as hard as I can. I know we have the best trainers and they’re going to be me in the best position possible [to] try and get back for [the] first week.”
