Brazil head coach Tite has confirmed Marcelo is back in contention for a place in his starting XI in Friday's World Cup quarter-final with Belgium after recovering from a back injury.
The Real Madrid left-back lasted just 10 minutes of Brazil's 2-0 Group E win over Serbia, when he was forced off with back spasms and replaced by Filipe Luis.
Marcelo subsequently missed the 2-0 defeat of Mexico in the last 16 and Filipe Luis generally looked assured, even if Hirving Lozano caused him a few issues.
Tite did not confirm whether or not Marcelo will return to his starting XI, but he is ready to make a comeback in Kazan.
