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:
9. Josh Windass - 8
Was a real handful for Luton, caused plenty of problems down the right side, put some dangerous balls into the box, and wasn't too far from getting on the scoresheet either. | UGC
10. Olaf Kobacki - 7
Came so close to getting on the scoresheet in the first half with a lovely curling effort, but was also very good in his defensive efforts as well. Not a bad outing at all. | UGC
11. Michael Smith - 8
Worked tirelessly up top for the Owls, won plenty of duels and was a real focal point at the top of their attack. A good outing from the big man. | UGC
12. Djeidi Gassama - 7
Came on at the break for Kobacki and immediately caused problems. Would've had an assist for Windass if it wasn't for some excellent defending. Had to come off when the Owls went down to 10. | UGC
