Sheffield Wednesday caretaker manager Neil Thompson has admitted Callum Paterson was about to be substituted before scoring the team's winning goal in the 1-0 victory over Derby.
With the hour mark approaching, Jordan Rhodes was being readied to replace the Scotland international, but he reacted by scrambling in the only goal of the game against Derby before eventually being replaced 10 minutes later.
Thompson, who was celebrating a second victory in four days following the sacking of Tony Pulis, revealed: "Callum was going to come off because he had run himself into the ground.
"He was absolutely shot to bits, but the goal energised him, so we gave him another five or 10 minutes, even though Jordan was champing at the bit to go on".
Former York and Scarborough boss Thompson added he did not know whether this match would be the last of his temporary tenure, saying: "When managers change it's disruptive and difficult for players, but the bottom line is this is their job and they've got to go out and perform. We just try and give them a bit of structure and information."
Derby interim boss Wayne Rooney felt his side were denied a stoppage-time penalty for handball, but also accepted his players did not take advantage of their early dominance of the game.
"I don't need to see a replay of the handball, because I could see it from the dugout and the fourth official did as well, so I don't know why he isn't allowed to communicate with the referee, because they can't be expected to see everything.
"It was a very frustrating game. We dominated the first 30 minutes and made some good chances, but failed to take them and we then allowed ourselves to get drawn into a game that Sheffield Wednesday wanted and that cost us."
The win lifted Wednesday to 20th in the league, one spot above Derby on goal difference but with the Rams enjoying a game in hand.
