Kaspars Gorkss' sending-off at QPR on Sunday has been overturned on appeal.
The Reading defender was shown a straight red card for a late tackle on Rangers' Junior Hoilett during a 3-1 win at Loftus Road.
Gorkss - sent off at Middlesbrough earlier in the season - was facing a four-match ban, but Reading's appeal has been upheld.
A Football Association statement read: "Following an Independent Regulatory Commission hearing today, Reading's claim of wrongful dismissal regarding Kaspars Gorkss was upheld.
"Gorkss was dismissed for serious foul play during the game against Queens Park Rangers on 16th February 2014. His standard suspension has, therefore, been withdrawn with immediate effect."
Gorkss will now be available for Saturday's Championship game against Blackburn.
