GREEN BAY, Wis. — Dovonte Edwards made the dream play of his young NFL career.

Somebody better pinch the Minnesota Vikings rookie, because this time he was wide awake.

Edwards intercepted a pass from Brett Favre and returned it 51 yards for a touchdown, Paul Edinger kicked a 27-yard field goal as time expired, and the Vikings kept their playoff hopes alive with a 20-17 victory over the Green Bay Packers on Monday night.

"I had a dream actually last night that I would do something big today and it came true," Edwards said. "Mike Tice said you need to dream, dream about making plays and that's what I did last night and it happened for me tonight."

Favre staked the Packers to a 7-0 lead on a 15-yard touchdown pass to Donald Driver in the back of the end zone in the first quarter. With Green Bay driving again with just more than a minute left in the half, Edwards stepped in and changed the game.

Favre, who was 11-for-14 for 112 yards at that point, looked right and fired a pass to Andrae Thurman, one of the Packers' many reserve players forced into action during a season littered with injuries.

"I just read the quarterback's eyes the whole way," Edwards said. "I broke before the receiver did."

Edwards made a diving interception, bounced up and ran before somersaulting into the end zone to tie the game at 7.

The play was reviewed to see if Thurman might have touched Edwards down. Edwards knew he hadn't.

"I felt he didn't touch me when I was on the ground," he said. "I just reverted to my old wide receiver days and took it to the house."

Favre struck back with a 53-yard TD pass to Driver, who slipped past cornerback Antoine Winfield on a post route and outran former Packers safety Darren Sharper with 26 seconds left in the half to take a 14-7 lead.

But the momentum wouldn't stay on Green Bay's side: Favre was just 5-of-15 from that point for 47 yards and another interception.

On their second possession after halftime, the Vikings went on a 13-play, 88-yard drive — helped by three Packers penalties — that was capped by Ciatrick Fason's 1-yard touchdown run to tie the game. Minnesota hadn't scored an offensive touchdown in eight quarters.

After Edinger gave the Vikings a 17-14 lead in the fourth with a 24-yard field goal, Favre led the Packers on a tying drive — capped by Ryan Longwell's 46-yard kick with 3:03 left.

That turned out to be too much time, and the Vikings easily moved back into range for the winning kick.

Edinger's field goal marked the second time he's beaten the Packers this year as time expired. Longwell did the same thing in both regular-season games last year.

The win puts the Vikings at .500 for the first time this season and keeps them in the postseason hunt, two games behind NFC North leader Chicago (7-3).

Meanwhile, the loss puts the Packers (2-8) on the verge of ending an impressive streak — they haven't had a losing season since Favre took over as starter in 1992, a run of 13 years that's best in the league. They have to win out to avoid snapping that run, an unlikely task with Chicago (twice) and Seattle (8-2) left on the schedule.
