The good news for the New York Jets from last night?

They beat the Buffalo Bills 19-13 in Toronto to move to 6-6 and keep their playoff hopes afloat.

The bad news?

For the second time in five days, rookie quarterback Mark Sanchez injured one of his knees.

Sanchez limped off in the third quarter in didn't return after diving headfirst on an 8-yard run.

Jets coach Rex Ryan, for one, was a little disappointed that the 23-year-old didn't slide on the play. After all, he was treated to a private lesson on the subject this week by Yankees manager Joe Giriardi.

"He's got to understand I don't care about the first down," Ryan said. "I care about him." He added, "I never want him diving forward. I thought we were clear on that."

Sanchez said in the heat of the moment that he just lunged for the first down, and he knew he would take heat from Ryan for doing it. Ryan said that if Girardi were watching, he would have called Sanchez a "knucklehead."

"He's our knucklehead and we love him," Ryan said. "But man, oh, man."

This morning, ESPN's Adam Schefter reports that the quarterback has a sprained PCL, and will be able to play in the Jets' Dec. 13 game if he's able to handle the pain.
