Brazil's doctor says it's too early to know if defensive midfielder Paulinho will recover from a left ankle sprain in time for the match against Italy at the Confederations Cup on Saturday.
.
Jose Luiz Runco says that although the injury is not serious, it could keep the player from being fully fit for the Group A match in Salvador.
.
Both teams have already secured a spot in the next round, but the match will decide the group winner and determine who gets to play World Cup Spain in the semifinals.
.
Runco said Thursday that defender David Luiz will undergo tests on his nose after he injured it in the team's 2-0 win over Mexico on Wednesday, but is expected to play against Italy regardless of the extent of the injury.
