The Owls put in an excellent performance in the first half as they went away to the former Premier League outfit, and they took the lead in the second half thanks to an excellent Barry Bannan strike - they thought they were en route to victory, and it would have been deserved.
But Di’Shon Bernard was adjudged - contentiously - to have handballed in the box, a penalty was given and Carlton Morris scored from the spot to level up before bundling home a second that gave the hosts all three points. Wednesday deserved more, and should be buoyed by how they performed.
Here’s how we rated the Owls after their bitter afternoon in the capital:
13. Svante Ingelsson - 7
Came on just after the hour mark to take Bannan's place in the midfield. Got booked not long after coming on, but went about his job well enough and tried to make things happen. | UGC
14. Iké Ugbo - 6
Replaced Smith as the Owls headed into the final half hour, worked hard up top but was on for a large period when the game had shifted in Luton's favour. | UGC
15. Michael Ihiekwe - N/A
Came on for Gassama after Bernard's sending off to plug the gap in defence. | UGC
16. Anthony Musaba - N/A
Came on as a last throw of the dice heading into added time. | UGC
