It means that from a fairly solid and - dare we say it - predictable few weeks on the Owls selection front, there are suddenly a whole host of possible permutations depending on how the likes of George Byers, Lee Gregory, Josh Windass and Reece James get on over the next 24 hours.
Wednesday’s is a relatively tight-knit squad and though there might be a little bit of nervousness around how they go about things, there’s no doubt this Owls side has battled adversity of all types this season - taking a lighter squad at Oakwell would just be the latest to navigate.
Based on a gut feel of who may-or-may-not be available, here’s the side we can see lining up at Barnsley on Tuesday evening.
5. RWB - Liam Palmer
Back-three? Wide right? The man could probably stick the gloves on and do a job such has been his form so far this season. Jack Hunt played on Friday and did OK but probably not enough to kick the door down. With Iorfa back, Palmer will likely shift out wide. Photo: Steve Ellis Steve Ellis
6. CM - Will Vaulks
Blessed the combative skills and work rate that will no doubt come in handy during a midweek derby ding-dong, He’s vitally important in every way. Photo: Steve Ellis
7. CM - Barry Bannan
Continues to tick things over nicely. There’s a perception perhaps that Wednesday are not as reliant on Bannan these days and while that’s true in the sense that others can create opportunities going forward, he’s still very much the main man in so many metrics. A class act. Photo: Steve Ellis Steve Ellis
8. CM - Dennis Adeniran
A player who has rarely let Wednesday down when he has been fit, Adeniran is the player we’ve plumped for in midfield - assuming Byers is still out. The combination is one rarely seen, there are concerns over his defensive aptitude and the likes of Tyreeq Bakinson and Fisayo Dele-Bashiru are fair shouts, but the former Everton man is full of energy and may well have a point to prove.
