While the Terriers and Blues sit seven and five points ahead of Rotherham United, the 22nd-placed side in the division have two matches in hand.
With speculation intensifying regarding his long-term future at St Andrew's, Aitor Karanka has needed to consider whether he should take the shackles off this underperforming yet talented squad.
Although there has been little difference in terms of quality, Blues have claimed two wins from three matches, the second ending a long-standing period without success at their home ground.
Birmingham fans have had to remain patient for the former Barcelona youngster to make an impact, but the playmaker's 20-yard winner could act as the catalyst for a more successful end to the season.
While Birmingham are showing signs that they are on the up, supporters of Huddersfield will be frustrated that they find themselves in the same position as they were under Danny Cowley 12 months ago.
The Terriers have had their ups and downs under Carlos Corberan, the club initially seeming comfortable in mid-table after overcoming a slow start under the Spaniard.
However, collecting just five points from 11 games is by far the worst return in the division over that period, and it has left club officials fearing a return to League One.
Despite last weekend's 4-1 triumph over promotion-chasing Swansea City, Huddersfield have been brushed aside with minimal fuss by Derby County and Preston North End.
The intention had been to build a project under Corberan with a number of years in mind, but the powers-that-be could be forced into a change if Huddersfield succumb to a ninth defeat in 12 outings on Tuesday night.
Huddersfield Town Championship form: DLLWLL
Birmingham City Championship form: LLLWLW
While a change in strategy contributed to Birmingham's win at the weekend, Karanka may insist on starting with a more cautious approach.
Huddersfield Town possible starting lineup:
Schofield; Stearman, Keogh, Sarr; Pipa, Vallejo, O'Brien, Rowe; Mbenza; Campbell, Holmes
Birmingham City possible starting lineup:
Etheridge; Colin, Dean, Roberts, Pedersen; Harper, Sunjic, Gardner; Sanchez, Hogan, Bela
We say: Huddersfield Town 1-1 Birmingham City
A win for either team on Tuesday could potentially change their season, putting them within touching distance of getting out of trouble. However, despite the rewards on offer, both managers will first want to avoid defeat, and that could lead to a low-scoring draw.
