Al Del Greco kicked two fourth-quarter field goals, the second with seven seconds remaining, to lift the Green Bay Packers to a 20-17 NFL victory today over the Minnesota Vikings.

Del Greco's 22-yard game-winner ended a 66-yard drive that started with less than 1 1/2 minutes to play. The big play was a 26-yard pass from Lynn Dickey to James Lofton to the Minnesota 10. A roughing-the-passer penalty on defensive end Mark Mullaney gave the Packers (3-3) a first and goal with 16 seconds remaining. Del Greco's kick came on second down.

Dickey, who played with a badly bruised thumb on his passing hand, completed five passes on the drive.

"I was more ready this game than any other this season, but the whole day was a struggle," Dickey said. "My hand was hurting, I couldn't grip the ball as well and, as a result, they were batting down my passes on a number of occasions."

Green Bay took a 14-7 third-quarter lead one play after Minnesota linebacker Scott Studwell intercepted Dickey's pass in the end zone and returned it to the Vikings' 12-yard line.

Minnesota running back Darrin Nelson then fumbled on a hit by defensive end Robert Brown, and cornerback Tim Lewis took the ball six yards for a touchdown.

The Vikings (3-3) tied it at 14 on a 43-yard pass from Tommy Kramer to wide receiver Leo Lewis. Following an interception by linebacker John Anderson, Del Greco kicked a 45-yard field goal to make the score 17-14 with 10:31 remaining.

Jan Stenerud kicked an 18-yard field goal with 1:24 left after the Vikings failed to score on three plays inside Green Bay's five-yard line.
