Sanchez didn't slide, and now he's out

TORONTO -- For the second game in a row and second time in a five-day span, New York Jets rookie quarterback Mark Sanchez left the game with a knee injury.

SanchezSanchez limped off the field because of an apparent right knee injury with about eight minutes left in the third quarter of Thursday night's game against the Buffalo Bills in the Rogers Centre. He was replaced by Kellen Clemens and walked back to the locker room under his own power, presumably for tests.

Sanchez briefly exited Sunday's victory over the Carolina Panthers because of a left knee injury.

The scare prompted the Jets to seek a special tutor to teach Sanchez how to slide feet first. New York Yankees manager Joe Girardi showed up at the Jets' facility Tuesday, and by all accounts the instruction took.

But Sanchez might've gotten hurt on a head-first dive at the end of an 8-yard, first-down scramble two plays before he took himself out of the game.

Sanchez's return has been announced in the Rogers Centre press box as "questionable." The Jets lead the Bills 16-10 through three quarters.
