Brazil striker Hulk will miss training again and is doubtful for the team's World Cup match against Mexico on Tuesday.

The Brazilian football federation says no serious injury was detected in an MRI scan on Monday, but the player will not join the rest of the squad for training at the Arena Castelao, where Brazil plays its second World Cup match.

The federation said a decision on whether Hulk can play will only be made on Tuesday after doctors re-evaluate his condition.

The forward left the field less than 15 minutes into Sunday's practice session in Brazil's training camp in Rio de Janeiro.

Hulk said he has had the injury since before the opening Group A win against Croatia, when he was substituted late in the second half.
