Nottingham Forest must put the disappointment of missing out on automatic promotion behind them as they travel to South Yorkshire to face Sheffield United in the first leg of this play-off semi-final.
The Reds pushed Bournemouth for second place, and it's been a great season considering Forest were bottom of the Championship after eight games, so Steve Cooper's side must concentrate on this opportunity and forget about the past two games (L1, D1).
Before losing to Bournemouth, Forest had only lost one of their previous 15 Championship games, and they'll need to carry that form into the play-offs if they want to end their 23-year top-flight exile.
After failing to progress through the play-offs in their previous eight attempts, the Blades will be looking to make amends this season by returning to the Premier League at the first time of asking after being relegated last season.
If Billy Sharp recovers from a calf tear, he is the lone player on that list who could be in contention. At the end of April, Heckingbottom said: "You can understand why I am not going to tell you when I am speaking to you before. It's not good news and it's going to be weeks rather than days."
Nevertheless, Heckingbottom recently told the local media that Sharp is "another few days closer".
With his team limited on attacking alternatives, the Sheffield United manager may be forced to risk the veteran striker for the first leg.
Forest manager Steve Cooper has known his best starting lineup for months and will hope to revert to the lineup that faced Bournemouth recently.
When it comes to injuries, though, Steve Cooper has a lengthy history of stating the worst-case scenario.
When Keinan Davis was first injured, there was speculation that he would be able to return in time for the playoffs, but that remains to be seen.
Sheffield United: Foderingham; Basham, Egan, Robinson; Osborn, Norwood, Fleck, Stevens; Berge; Ndiaye, Gibbs-White
Nottingham Forest: Samba; Worrall, Cook, McKenna; Spence, Yates, Garner, Colback; Zinckernagel; Johnson, Surridge
