The hosts held Hertha Berlin to a goalless stalemate in their most recent outing, while mid-table Hoffenheim enjoyed a comfortable win over Schalke 04.
An inconsistent but largely solid run of results since the turn of the year has Arminia firmly in a capable position to avoid an immediate demotion back down to the 2. Bundesliga, but Frank Kramer's men have just two games remaining to try to climb out of the bottom three.
Since replacing Uwe Neuhaus at the helm, Kramer has endured a mixed bag of results - three wins, four draws and three defeats from his opening 10 games in charge - but a 0-0 draw with a rejuvenated Hertha Berlin side can certainly be viewed as a positive result.
Arminia's tally of 31 points from 32 matches sees them occupy the relegation playoff spot as things stand, with 17th-placed Koln just two points behind Kramer's side, while Werder Bremen are only ahead of their relegation rivals on goal difference with two games to go.
Kramer has overseen just one defeat in his last six games in charge of Arminia - a 5-0 hammering at the hands of Borussia Monchengladbach - and four of those matches have ended with Arminia and their new-found defensive resilience keeping clean sheets.
The hosts have not managed to string three consecutive home wins together all season, but back-to-back 1-0 victories over Freiburg and Schalke 04 has instilled belief that a crucial win could be on the cards here, especially seeing as Hoffenheim have nothing to play for anymore.
With the pressure off as the season draws to a close, Hoffenheim's fortunes have taken a turn for the better in weeks gone by, but it is far too late for Sebastian Hoeness's side to make those results count for anything worthwhile.
A resounding 4-2 win over relegated Schalke last time out saw Hoffenheim stretch their unbeaten run to five games, as Andrej Kramaric, Christoph Baumgartner, Kevin Akpoguma and Ihlas Bebou made the net ripple on the day.
A top-half finish is not beyond Hoffenheim's reach at this very late stage, but five points separate them from ninth-placed Freiburg, and there is little reason for Hoeness's side to go all out and risk exacerbating their injury problems before the campaign concludes.
Nine points taken from the last 15 on offer is a positive step forward, though, but the only two wins in that sequence have come on home soil, with Hoeness aiming to end a seven-game winless run on the road stretching all the way back to January this week.
The first meeting between these two sides earlier in the season ended goalless, and the only previous clash on Arminia's turf came all the way back in the 2008-09 season, during which Hoffenheim secured a comfortable 2-0 win.
Japanese midfielder Masaya Okugawa had to come off with a knock after 74 minutes against Hertha, though, and it remains to be seen if he will be given the green light to play despite taking part in training.
Hoffenheim's injury list is far more alarming by comparison, with Benjamin Hubner, Ermin Bicakcic, Dennis Geiger, Oliver Baumann and Chris Richards all likely to miss the final two games of the season.
Baumgartner will also sit this one out after sustaining an ankle injury during training, while striker Munas Dabbur has returned to Israel for personal reasons.
Few changes can be expected on the visitors' end following their comfortable win over Schalke, but a change in formation could see Sebastian Rudy come back into the midfield as Robert Skov fills in for Baumgartner on the left.
Arminia Bielefeld possible starting lineup:
Ortega; Brunner, Pieper, Nilsson, Lucoqui; Prietl, Maier, Vlap; Doan, Klos, Voglsammer
Hoffenheim possible starting lineup:
Pentke; Kaderabek, Posch, Akpoguma, Sessegnon; Samassekou; Bebou, Grillitsch, Rudy, Skov; Kramaric
We say: Arminia Bielefeld 1-1 Hoffenheim
Arminia have far more to play for than Hoffenheim do at this stage and are not going down without a fight, so we anticipate a close affair this weekend.
Despite a recent upturn in results, Hoffenheim continue to struggle for form away from home, and we can see Kramer's hosts doing enough to claim another point in the battle to avoid the drop.
