Manchester City will be without their captain Vincent Kompany for four matches after failing to have his red card overturned.

33335 - Manchester City fail in appeal over Kompany red

Kompany was given his marching orders just nine minutes into City's FA Cup third round defeat to Manchester United on Sunday after a two-footed challenge on United winger Nani.

City manager Roberto Mancini accused Wayne Rooney of influencing referee Chris Foy's decision, but the Football Association has upheld the original decision.

A statement on the FA website said: "An Independent Regulatory Commission has today dismissed a claim of wrongful dismissal from Manchester City's Vincent Kompany following his red card for serious foul play in The FA Cup third round tie between Manchester City v Manchester United on 8 January 2012.

"Kompany will serve a four-match suspension with immediate effect. The suspension consists of a statutory three-match suspension for serious foul play plus one additional game given this is Kompany's second dismissal of the season."
