Sergio Busquets hit the ground early and often in the first leg of the Supercopa de Espana both for good reasons and not so good reasons. In the 11th minute, he fell over a Xabi Alonso challenge and found himself in a familiar position right in the line of fire for Jose Callejon, who blasted the ball off Busquets' head from close range.
Ironically, it was only after this happend that Busquets covered his head and had he done it immediately upon hitting the ground, as he's known to do, maybe he could have blocked the impact.
Alonso was shown a yellow card for the challenge and Callejon went unpunished for kicking the ball. Busquets played the entire match, though he was in pain several more times.
