The corner from that came to nothing, but the message was clear.
Wigan, despite playing kids, hadn't thought about throwing the game away, and as halftime approached, the momentum stayed with the home side.
Duvan broke up one final Luton move with a crunching tackle that brought the crowd to its feet.
He rose calmly, nodded to a teammate just before the whistle for the break arrived, with the score still level, but the feeling inside the stadium told a different story.
Walking toward the concourse, fans talked animatedly.
"Look at them," one said. "I am getting really confident watching them play because if this is how our boys are coming along, sooner or later, we might get promoted even if we don't get that this season."
"That's a proper generation coming through," another replied. "If this is the future, we're in good hands."
