It was one of the biggest and ugliest collisions this week in World Cup qualifying play. Nicolás Burdisso and Mark González bumping of heads left more than just a simple headache the following morning. Betis’ Mark González suffered a second-degree craneoencephalic traumatism and a third-degree knee sprain that will keep him out for three months. Part of his injury includes a tear of his medial collateral ligament and an MRI in the coming days will confirm the true extent of the injury. Betis doctors would like to see González come back to Spain to get a second opinion and a clearer diagnosis of his situation. Speculations state that he could be ready to play in about three weeks if he avoids going under the knife.
