Arsenal's Jose Antonio Reyes has been given a three-match ban by the Football Association for violent conduct in Saturday's game with Sheffield United.
Reyes, 21, was found to have struck Andy Liddell after an incident between Danny Cullip and Cesc Fabregas in the FA Cup fifth-round tie which ended 1-1.
The offence was missed by referee Neale Barry, but the FA brought the charge after looking at video evidence.
Reyes will miss the replay and league games with Southampton and Portsmouth.
Team-mate Dennis Bergkamp was sent off for his involvement in the incident and had already been banned for the same three games.
The double blow leaves manager Arsene Wenger in a difficult situation, with only Thierry Henry and Robin van Persie available as senior strikers.
