The match between Brazil and Serbia started with terrible news for the South Americans, as their starting left-back Marcelo was forced off the pitch due to a back spasm, making him the third Brazilian player to get injured at this World Cup.
Marcelo asked for the change just nine minutes into the game after his one-on-one race with speedy midfielder Sergej Milinkovic-Savic.
At first, it did not seem serious, but when he received the ball he noticed he was in pain and he immediately stopped.
Neymar quickly ran to the defender, but the signs were clear and he could no longer continue.
Brazil coach Tite brought on Filipe Luis to take the spot of Marcelo, with the Atletico Madrid left-back making his first World Cup appearance.
Filipe Luis is a reliable player, but the loss of Marcelo is a huge blow for one of the favourites of the tournament.
Marcelo’s injury also highlights the muscle problems that Brazil have been suffering from during this World Cup.
This is the team’s third injury at this World Cup, after also losing Danilo and Douglas Costa.
