Not impressed.

France have called for World Rugby to investigate a photo of referee Jaco Peyper that has been doing the rounds on social media since yesterday.

In the photo, the South African referee appears to mock the elbow to the head that earned Sebastien Vahaamahina a red card in yesterday’s Rugby World Cup quarter-final clash between Wales and France.

“This photo, if it is true, is shocking and explanations will be necessary,” French Rugby Federation vice president Dr Serge Simon said on Twitter.

Wales head coach Warren Gatland meanwhile backed Peyper’s decision to issue the red card on the day.

“The officials dealt with it appropriately. I don’t think anyone could complain about that. The right decision was made,” Gatland said.

As did his France counterpart Jacques Brunel.

“The red card I don’t contest – when you see the images it’s very clear. He did have contact with the face so we can’t deny that,” Brunel said.

World Rugby meanwhile have acknowledged they are aware of the photo.

“World Rugby is aware of a picture on social media of referee Jaco Peyper with a group of Wales fans taken after last night’s quarter-final between Wales and France in Oita,” a spokesperson said.

“It would be inappropriate to comment further while we are establishing the facts.”
