Ken O'Brien threw three touchdown passes, two to tight end Mickey Shuler, to help the New York Jets defeat Buffalo, 27-7, today. It was their second victory over the Bills this year.

New York (10-4) remained in a three-way tie with the Miami Dolphins and New England Patriots for first place in the AFC East.

O'Brien, who completed 25 of 40 passes for 370 yards, passed 20 and two yards for touchdowns and also threw a team record 96-yarder to Wesley Walker. It was the longest pass completion in Jets history.

"We were backed up there pretty tight," Jets Coach Joe Walton said. "I thought it was the right time and the right situation to try for the long gainer."

Johnny Hector also scored in the second quarter for the Jets on a 12-yard run. Only Greg Bell's eight-yard touchdown run saved the Bills from a shutout.

The Bills, the NFL's lowest-scoring team, had three long drives stopped by turnovers, once when they fumbled on the Jets' one and again when Bruce Mathison's pass was intercepted in the end zone.

Mathison was knocked from the game twice by defensive end Mark Gastineau, but not before becoming the second quarterback to pass for more than 300 yards in a game against the Jets, finishing with 357. He was replaced each time by Frank Reich, the rookie from Maryland.

Buffalo had the game's first extended drive, moving from its 12 to the Jets' 39 before Booker Moore fumbled the ball and Gastineau recovered. O'Brien's scoring pass then gave the Jets a 7-0 lead.
