Ben Roethlisberger led a Super Bowl-like 86-yard drive in the final two minutes that ended with no time left when Mike Wallace caught a 19-yard touchdown pass as the Steelers beat Green Bay 37-36.
Wallace's catch even mimicked the one Santonio Holmes made to win Super Bowl XLIII in February.
Jeff Reed's extra point kick provided the winning margin.
The victory ended a five-game losing streak and raised the Steelers record to 7-7. Green Bay's five-game winning streak ended and the Packers are now 9-5.
Roethlisberger passed for a team-record 503 yards, three touchdowns and no interceptions.

The Steelers took over at their 14 after a bobbled kickoff return with 2:06 left and moved 86 yards on 12 plays for the winning score.
