Arsenal midfielder Jack Wilshere will serve a two-match ban for an abusive hand gesture.
The 21-year-old had admitted to the charge leveled against him by the Football Association but contested the mandatory length of ban.
An independent regulatory commission rejected his appeal after hearing on Thursday.
An FA statement said: “Whilst admitting the charge, Wilshere claimed the standard sanction for this offence was clearly excessive.
“The commission rejected this claim and the two match suspension will commence with immediate effect.”
Television pictures appeared to show Wilshere raising the middle finger towards the crowd during last Saturday’s 6-3 loss to Manchester City at the Etihad stadium.
Though the match officials did not notice the incident but was caught on video and assessed by the FA retrospectively.
Wilshere will miss Monday’s top-of-the-table clash against third-placed Chelsea at the Emirate stadium and the Boxing Day fixture against West Ham.
Very useless behavior and this serve as a lesson and warnings to the rest players
