Owls boss Stuart Gray could be forced to gamble on giving 20-year-old new signing Adedeji Oshilaja a Championship debut at Reading today.
The loan centre half will be on stand-by to play in case Glenn Loovens fails a check on his problem hamstring.
It would be a big step up for Oshilaja, whose only League football has been eight games while on loan with League Two outfit Newport County this season, the last of them against Burton on December 29.
He has also played two games for Newport in the FA Cup and two in the Johnstone’s Paint Trophy.
His only first-team games for Cardiff were last season: their shock 2-1 FA Cup defeat at Macclesfield, who were knocked out by Wednesday this season, and their Capital One Cup 2-1 exit at Northampton.
His loan deal runs to March 12. He was born in London and came through Cardiff’s academy.
If Loovens is ruled out, the Owls will have Miguel Llera as the only fit member of their own centre-half pool.
Gray has also been trying to bring in a striker to boost firepower - and Atdhe Nuhiu admits that he is under pressure to score more goals after netting only three times this season.
But the Owls centre forward bears it as part of the job and insists that he is not unduly worried so long as the team are winning.
Nuhiu also feels that Gray appreciates his hard graft and contribution to the team even when he is not scoring.
“Three goals and two assists...I know I have to score more goals, this is fact,” he admits. “But we worked hard to win games. I will work hard to score. The most important thing was to win. This has brought us out of the relegation zone because we are a team and it doesn’t matter who scores.
“Always as a striker you have pressure but you have to be strong enough to take it. I learned this at different clubs, so it is not something new for me. You have to face that, and no problem.
“What I want to know is that the managers appreciates (me); I think he does. You have to maybe do the ‘black work’ and the other guy scores. I don’t mind, if we win.”
The Austrian says that confidence and team spirit are flourishing: “We have to keep going like this. I think we have also shown that we don’t have to worry about any team. I am am confident enough to say we can beat anybody. Our run will hopefully continue.”
Although the Owls have been trying to bring in players, they are well blessed for keepers and that is why they have let Cameron Dawson join Plymouth on loan for the rest of the season.
Oshilaja is with Wednesday until March 12.
