Sergio Busquets definitely did not fake this injury

We've all made jokes about Sergio Busquets' habit of falling down and clutching his face for no good reason, but this time it was his knee and he wasn't faking.

A mere seven minutes after entering Barcelona's 2-1 win over Real Sociedad in the 76th minute, Busquets was accidentally stepped on by Carlos Martinez, opening up a deep gash under his right knee.
