Wigan, England – Wigan striker Conor Sammon had his red card game suspension as a result.
Sammon was sent off in the 5-0 loss to United after hitting Michael Carrick in the face, but Wigan's claim for wrongful dismissal was upheld as Sammon's act was not deliberate.
"We thank the panel for their decision, which is the correct one. We now need to draw a line under the matter and move on," Wigan manager Roberto Martinez said. "I am delighted to have Conor available for the next three matches.
"It would have been really unfair for him to share the frustrating feeling that he had on Monday for another three games after doing nothing wrong."
Sammon will be available to face Stoke City on Saturday. Wigan is 18th in the English Premier League, just three points off the bottom.
