Steve Breitkreuz is adjudged to have downed Schimmer and the ref points to the spot. A quick check and the spot kick stands.

We'll have eleven minutes added to the end of this game!

Jahn get the second half underway.

Hats off to the hosts. They know they need the miracle of all miracles to avoid relegation here. A win and a 15 goal swing are among the factors required for the Red Shorts to survive but they're making a right go of it in front of their own fans. Heidenheim, not so much.

Frank Schmidt takes advantage of a brief water break to issue Jan-Niklas Beste with some important instructions. Heidenheim need a spark of inspiration from somewhere.

Heidenheim are making most of the early running here but the visitors have failed to produce a big chance against a Jahn side looking to counter.

News filters through of an early goal for Hamburg in their game at Sandhausen. As things stand, HSV leapfrog Heidenheim into the automatic promotion spot.

Heidenheim get the match underway! Will the visitors be celebrating with a first-ever promotion to the Bundesliga at the end of this one?

It's a stunning day in Bavaria as both teams make their way out onto the pitch. We're moments away from kick-off.

The Jahn club song is belting out as the teams gather in the players' tunnel, high-fiving as they line up.

Both teams are coming to the end of their respective warm-ups at the Jahnstadion Regensburg. There's a superb atmosphere inside the ground for this huge Bundesliga 2 encounter.

Heidenheim certainly have the edge in terms of recent form on their opponents today. The visitors are unbeaten in six and have won the last four meetings between the teams.

Urbig - Saller, Breitkreuz, Kennedy, Guwara - Thalhammer, Gimber – Faber, Albers, Yildirim - Owusu

Kirschbaum, Nachreiner, Elvedi, Idrizi, Singh, Shipnoski, Schönfelder, Mees, Graf

Müller - Busch, Siersleben, Mainka, Föhrenbach - Schöppner, Maloney - Pick, Thomalla, Beste - Kleindienst

Eicher, Theuerkauf, Geipl, Sessa, Burnic, Beck, Keller, Schimmer, Kühlswetter

Heidenheim cannot finish lower than third, which would ensure a two-legged play-off against the team that finishes 16th in the Bundesliga (one from Schalke, Bochum, VfB Stuttgart or Augsburg). Frank Schmidt's side contested the winner-takes-all tie back in 2019/20, losing out to Werder Bremen on away goals. If Regensburg pull off mission impossible, meanwhile, they'll get a reprieve via a two-legged tie against 3. Liga opposition.

Regensburg forward Charalambos Makridis - who scored his third goal of the season in the win against Eintracht - is suspended, but defender Steve Breitkreuz is available again following a one-game ban. For their part, Heidenheim should have Norman Theuerkauf back from illness.

Heidenheim will be promoted if they equal or better Hamburg's result away at relegated Sandhausen, or lose by fewer than six goals and HSV draw. As for second-bottom Regensburg, they cannot achieve automatic safety and will only reach the play-off if they win and Arminia Bielefeld lose at Magdeburg with scores that achieve a 15-goal swing.

In the third tier as recently as 2014, Heidenheim are one win from a maiden promotion to the Bundesliga. Anything else, and they'll be reliant on third-placed Hamburg dropping points at relegated Sandhausen. Stay tuned!
