Shane Duffy refused to use a mounting injury list as an excuse for Norwich City's Sheffield Wednesday no-show. 

The depleted Canaries were short of several key players and produced an under-par performance at Hillsborough, which resulted in a successive Championship defeat against Danny Rohl's side. 

Despite notching over 70 percent possession, City were toothless in attacking moments and lacking in purpose with their play on the ball, much to Johannes Hoff Thorup's frustration. 

Defensive and goalkeeping errors compounded a difficult evening where two costly first-half mistakes gift-wrapped the game for Sheffield Wednesday, who themselves were searching for a response after a heavy defeat at the weekend. 

But despite the obvious fitness mitigation, Duffy is refusing to use a nine-man injury list as an excuse for the level of performance on Tuesday night. 

"It's what you have a squad for, and it's up to others to step up. It's been difficult this week, but we cannot keep giving goals away. It's not about the squad or none of that - we gave really bad goals away, and that is the fact," the stand-in City captain said. 

"We were dominating the game early on, but one ball from the halfway line, and we're one goal down. Then they swing a ball in, and it goes in. It's frustrating. 

"We cannot really say that is down to a lack of squad - it's individual mistakes again, and it's cost us.

This is what football is all about. Everyone knows there are going to be injuries during the season to our key players, but it's opportunities for others. 

"That's what we have a squad for. We have to keep building on that. The reality is that this is us going forward for a while.

"Obviously, we'll get Kenny back from suspension, Nacho and Gunny back soon, but we've got another massive game Saturday with the same team and squad, so we've got to put this behind us quickly."
