Low has said that he is expecting a physical encounter in Belo Horizonte, after Brazil committed 31 fouls in their quarter-final victory over Colombia.
"They're playing more robustly than any other team here," he told BBC Sport.
"There's little left of that traditional Brazilian style of football. At the end of the day it's up to the referee to come up with the correct punishment."
Scolari's side have committed 96 fouls in total at the tournament, picking up 10 yellow cards in the process.
