VIDEO: Why does Gavi wear a helmet?

Barcelona midfielder Gavi suffered an ear injury in the 'Cules' 1-2 win over Osasuna. Despite the seriousness of the injury, the Spanish midfielder was able to finish the game.
Osasuna's Ruben Garcia tried to dribble past him and accidentally elbowed him in the ear. It wasn't long before there was blood on his shirt as he was treated by the medicall staff. After a few moments on the sideline, he returned to the pitch with three staples in his lobe.
That's why while the wound heals, the player must train with Spain with a protective helmet. Take a look at Gavi's new look.
