FLORHAM PARK, N.J. -- With one quarterback change, the New York Jets may have affected the future of two quarterbacks -- Mark Sanchez and Tim Tebow.

The Jets will explore all options with Sanchez, including a trade, and the team plans to part ways with Tebow after the season, league sources said Wednesday.

It would be difficult to trade Sanchez because of an $8.25 million guarantee in 2013 in his contract. However, the Jets, who benched Sanchez this week in favor of the unproven Greg McElroy, are taking an open-minded approach and may be willing to start over at quarterback.

Responding to the trade speculation, Sanchez's agent and older brother, Nick Sanchez, said Wednesday night: "Mark is a Jet and he's going to support the Jets any way he can through the remainder of season."

Nick Sanchez declined to comment on next season.

Meanwhile, a clearly miffed Tebow, no longer masking his season-long frustration, left no doubt he's unhappy with his role. He will seek to play elsewhere next season, and the Jets appear willing to accommodate his wishes.

Upset he was passed over for the starting-quarterback job, Tebow spoke of the Jets in the past tense Wednesday, admitting he doesn't understand why they traded for him last March. Asked if he envisions returning to the team in 2013, he said: "I'm not sure. It's something we'll talk about after the season."

The backup quarterback is expected to ask out, clarifying, "I haven't asked for a trade yet" -- the word "yet" hanging in the air. He's signed through 2014.
