Brazil's squad returned to training Monday ahead of their World Cup opener against Morocco on June 13 in New Jersey.
Midfielder Ederson joined the group that day after arriving from Atalanta. He'll replace right-back Wesley, who suffered a thigh injury and won't play in the tournament.
Star forward Neymar remains sidelined on an individual recovery plan. The 34-year-old wasn't cleared for full training Monday as expected.
An MRI scan showed he needs more time before joining team sessions. But Brazil's medical team is encouraged by the results.
Doctors say the latest scan shows marked improvement from earlier assessments. They conducted those before the squad flew to the United States.
Neymar is aiming to return during the group stage. He could potentially feature against Haiti on June 19 or Scotland on June 24.
Brazil faces Morocco at MetLife Stadium in their first match. Experts view the clash as a marquee fixture in the opening round.
Both teams will be fighting to establish dominance in Group C early on. The meeting is expected to be competitive and closely watched.
