ORCHARD PARK, N.Y., OCT. 7 -- The Buffalo Bills returned a blocked kick for a touchdown for the second straight week tonight, highlighting a 24-point fourth-quarter surge that produced a 38-24 victory over the previously unbeaten Los Angeles Raiders.

The Bills, scoring three more points against Los Angeles than the Raiders had allowed all season coming in, were down by 24-14 before James Lofton caught a 42-yard touchdown pass from Jim Kelly with 8:37 to go. That began a run of 24 points in 6:03.

Buffalo forced a punt and Steve Tasker came through untouched to block Jeff Gossett's punt from the Raiders 46. James Williams scooped up the ball on one bounce and ran 38 yards for the go-ahead touchdown with 6:52 left.

The previous week, Nate Odomes's block of a field-goal attempt by Denver's David Treadwell was returned 80 yards for a touchdown by Cornelius Bennett. The Bills, who were trailing by 20-7 at the time in that game, added two more touchdowns -- scoring 20 points in 77 seconds -- and won, 29-28.

This time, after Williams put Buffalo ahead, Bennett forced and recovered a fumble by Jay Schroeder. The Bills capitalized with Scott Norwood hitting a 23-yard field goal with 4:07 left.

The Bills (4-1) sewed it up when Odomes stripped the ball from wide receiver Willie Gault and ran 49 yards for a touchdown.

Gault and Steve Smith caught touchdown passes for the Raiders (4-1), who also got a one-yard scoring run by Marcus Allen and a 19-yard field goal by Jeff Jaeger.
