Via the Telegraph: Madrid’s statement clarified the nature of Bale’s back problem. It read: “To claim that the player has a slipped disc on the L5-S1 vertebrae and a bulge on two others, is completely false. The player does not have a slipped disc. He has a small chronic disc bulge, which is extremely common among football players and by no means prevents him from carrying out his professional activity normally.”
Got to love the Spanish press, especially Marca.
