They revealed the damage and the 18-year-old will have an operation on Thursday.

City boss Gary Johnson said: "Everyone is gutted for Christian. It's hard luck on the lad."

"He added: "As I said on the night he will come back from this."

Ribeiro, who made his way through Bristol City's Academy, has three caps at U21 level.
