Wigan's preparations for the new Premier League season suffered a setback at Carrow Road as they lost 3-2 at League One Norwich - after twice being ahead.
The Latics went in front after just nine minutes through Charles N'Zogbia's cool finish, but the impressive Canaries were back on level terms before the break as Chris Martin sidefooted home Jon Otsemobor's cross after some poor defending on the right.
Wigan quickly regained the lead through Cho Won-Hee who produced a superb finish after being set up by Jason Scotland's clever pass.
But the hosts had the final word, quickly equalising through Martin's second goal of the game before grabbing a winner after 76 minutes when Simon Whaley slipped the ball past keeper Mike Pollitt.
