The Republic of Ireland youth international was lackadaisical in his back pass to Murphy Cooper, which Morgan Whittaker pounced on to give the home side a lead they never really looked like giving up. That said, Boro were limited to few chances themselves by a hard-working Wednesday performance.
The match, the penultimate away day in what has been a long and arduous Owls campaign, will not go down in the annals of history.
Here are our ratings from the Riverside.
5. Max Lowe - 6
Not quite as tidy in possession as in recent weeks but sought ways to open things up in front of him. Caused an issue going forward. | UGC
6. Tayo Adaramola - 7
Spritely early doors, testing the Boro defence. A couple of concentration lapses let him down a touch defensively. Recovered a chipped shot into an otherwise open goal in the last few minutes. | UGC
7. Marvelous Nakamba - 5
His first start in Owls colours and a rare outing - in the 14 matches he's been available for, he'd featured in only four. Dashed about and sought to disrupt but was at times half a yard off the pace. Off at the hour. | UGC
8. Jarvis Thornton - 6
A couple of errant passes in key moments, but by the same token managed to keep possession under pressure. Battld hard and stuck at his task. Off injured with just over 20 minutes to go. | UGC
