Manchester United-bound Fred has suffered a World Cup injury scare after limping out of Brazil's training session on Thursday with an ankle injury.
The 25-year-old is set to leave Shakhtar Donetsk for Old Trafford after the Premier League club announced they had agreed a fee to recruit the midfielder.
He has been included in Tite's World Cup squad but was forced out of a session at Tottenham's Enfield training base, with ice applied to his right ankle.
Brazil start their bid to win an unprecedented sixth World Cup when they take on Group E rivals Switzerland on June 17 - with a final warm-up game coming against Austria in Vienna on Sunday.
Fred suffered the knock before trying to carry on with the training session, only to then require treatment on the sidelines.
