Leicester City defender Patrick Kisnorbo looks likely to avoid a suspension after referee Phil Joslin admitted to being wrong in sending off the Australian.
Kisnorbo was dismissed during Leicester's 3-1 defeat at Ipswich Town on Tuesday night following a challenge on Pablo Counago.
On the advice of his assistant, Joslin awarded a penalty and also showed Kisnorbo a red card at Portman Road.
However, video evidence showed Kisnorbo had won the ball from Counago and that the incident also occurred outside the box.
Joslin has now admitted his mistake, with the Football Association expected to confirm the red card has been overturned at a meeting on Thursday.
It will free Kisnorbo to play against Hull City on Saturday, although Foxes boss Ian Holloway expressed his disappointment after the game, with the penalty having given Ipswich a 2-1 lead.
Holloway said: "The referee did agree to look at it, but even if my player is let off, what good is that to me?
"It wasn't a penalty. I thought it at the time and I've had it confirmed on a replay.
"The referee was overruled by his linesman and that's like me picking a team and then being overruled by my assistant.
"The whole incident was a complete kerfuffle, but the referee thanked me for keeping my dignity afterwards - and that's not easy for someone like me."
