The Paris Saint-Germain defender is suspended for his country's contest against Peru and is debating when to return to France
The Paris Saint-Germain defender was sent off in Brazil's World Cup 2018 qualifier against Argentina on Friday, meaning he is ruled out of Tuesday's contest against Peru.
Officials report 129 people were killed and another 99 remain critical as a result of Friday's atrocities in Paris.
And David Luiz is unsure whether to remain with the national team or head back to Europe.
"It's really very, very sad. I'm worried and still trying to understand what happened," he said.
