Alan Lee's second-half strike gave Ipswich their first away league victory of the season at Sheffield Wednesday.
Lee turned in Alex Bruce's cross after 71 minutes to give them their first win on their travels in 17 attempts.
Former Owls' midfield man Alan Quinn put Ipswich ahead in the fourth minute with a stunning 25-yard drive.
Marcus Tudgay put Wednesday level nine minutes later, firing in a loose ball from 15 yards, but Lee had the final say to give Ipswich the three points.

"We're in trouble at the bottom and we need to improve. We've

"Our general play in the first half was good. In the second half we had to dig in but I thought we deserved the three points.
"We've got to use this as a springboard now for bigger and better things. I believe we can go on a run and get in the play-offs."
