British politicians are pressuring FIFA to extend the same suspension reprieve given to US striker Folarin Balogun to England defender Jarell Quansah.
The move escalates a controversy fueled by public comments from US President Donald Trump, who admitted contacting FIFA President Gianni Infantino over Balogun's case. FIFA insists its judicial bodies acted independently.
Labour MPs Noah Law and Melanie Onn wrote to Infantino, citing FIFA's Balogun decision as a precedent to defer Quansah's automatic one-match ban following his red card against Mexico. They argued that inconsistent application of rules would undermine confidence in FIFA's disciplinary system.
Separately, the Chair of the UK's Culture, Media and Sport Committee, Caroline Dinenage, demanded FIFA urgently explain its Balogun ruling, warning it threatens to cast a shadow over the tournament.
The controversy marks the World Cup's biggest off-field issue. England face Norway in the quarter-finals.
