DETROIT (AP) - Henrik Zetterberg and Valtteri Filppula scored less than two minutes apart in the third period, and the Detroit Red Wings rallied again for a 3-1 victory over the San Jose Sharks on Tuesday night, forcing a decisive seventh game after trailing 3-0 in the pulsating second-round series.

San Jose must defend home ice Thursday night to avoid becoming the fourth NHL team to lose a best-of-seven series after leading 3-0. San Jose's Logan Couture scored early in the third period, but Zetterberg tied it with 9:22 remaining, and Filppula scored the winner with 7:28 left.

Darren Helm added an empty-net goal. Every other game in the series was decided by one goal.

Detroit scored the last three goals of Game 5 to win 4-3.
