Dave Krieg threw for two touchdowns and Seattle sealed Green Bay's seventh straight defeat, 30-24, today as Seahawks cornerback Terry Jackson intercepted one of Lynn Dickey's passes in the end zone with 24 seconds left.

Striving to keep from a 1-7 midseason mark, their worst start since 1975, the Packers moved from their 29 to the Seattle 10, but sacks by John Harris and Mike Fanning pushed Green Bay back nine yards. Jackson's interception followed.

Penalized 17 times, Seattle (6-2) had three touchdown passes called back, but it was a successful homecoming for Krieg, who grew up in Iola, Wis., a Packers fan.

"Today's game proved the ability of our football team, we're not to be denied," Coach Chuck Knox said of his AFC West contenders. " . . . We made some big plays, especially when our backs were straight up against the wall."

The game was only 19 seconds old when Dickey passed to Lofton for a 79-yard touchdown on the first play from scrimmage. The Packers went on to lead, 17-7, but Seattle went up for good after Terry Taylor intercepted Dickey at the Green Bay 15, setting up Eric Lane's scoring plunge late in the half.
