Brazil defender Marcelo believes team-mate Fred will recover from an ankle injury in time for the World Cup after describing the issue as "not that serious".
Fred – who is set to join Premier League giants Manchester United after a deal was agreed with Ukrainian champions Shakhtar Donetsk – hurt his ankle during Thursday's training session.
A scan may be required as Brazil and team doctor Rodrigo Lasmar monitor Fred ahead of Sunday's final World Cup warm-up match against Austria.
But Marcelo told reporters: "This is the World Cup. Everybody's training hard, working hard and there are these moments in training.
"But I believe it's not that serious, I believe it's not a big problem for us and I think he'll be back with us as soon as possible."
Brazil – led by head coach Tite – will face Switzerland (June 17), Costa Rica (June 22) and Serbia (June 27) in Group E at the World Cup in Russia.
