• Challenge left Crystal Palace’s Mateta with head injury
• FA claims standard three-game ban ‘clearly insufficient’

The Football Associated has requested that Millwall’s goalkeeper Liam Roberts receive an increased punishment for his challenge on Jean-Philippe Mateta that led to the striker receiving 25 stitches in his left ear.

Roberts was shown a red card for serious foul play eight minutes into Saturday’s FA Cup fifth-round tie, after running outside the area and raising his left boot in a high challenge on the Crystal Palace striker.
