Halftime observations from Bills-Jets

Posted by ESPN.com's Tim Graham

EAST RUTHERFORD, N.J. -- The Buffalo Bills keep falling apart.

The New York Jets started slowly then began to flex their muscles in the second quarter. They lead the Bills 13-3 at halftime.

Jets running back Thomas Jones has broken his personal record for longest carry twice, with runs of 64 and 71 yards, the latter going for the game's lone touchdown.

The Jets went into the game with an NFL-low four sacks, but the first time they got to Bills quarterback Trent Edwards they knocked him out of the game with a head injury early in the second quarter. Ryan Fitzpatrick replaced him.

The Bills, who scrapped their no-huddle offense, haven't tightened up in the penalty department. They lead the NFL in yellow flags and have committed six penalties for 49 yards.

Two of the Bills' penalties hurt them on the scoreboard. They made it to the Jets' 12-yard line, but a hold and a false start pushed them back before Rian Lindell kicked a field goal.

The Bills were called for 12 men on the field on a Jets punt. The 5 bonus yards gave the Jets a fourth-and-inches. They went for the first down, got it and extended a drive that resulted in a tying field goal.

The Jets must be holding their breath over nose tackle Kris Jenkins. He hobbled to the locker room with a knee injury. His return for this game has been labeled questionable.
