According to sources, Neymar is using initial technology developed by NASA (US National Aeronautics and Space Administration) to treat his right calf injury. Neymar has been training on an anti-gravity treadmill, allowing the striker to run with less impact on the injured area.
This device has been used by athletes for more than a decade and some Brazilian clubs have bought it for training.
According to the Brazilian Football Confederation, Neymar has recovered well from his calf injury. On June 8, the player underwent an MRI (magnetic resonance imaging), the results showed that he "is progressing well in the treatment process", raising hope that he will be able to participate in Carlo Ancelotti's squad to play at the 2026 World Cup.

Neymar will continue to follow the recovery schedule and fitness training program set by the Brazilian national team's medical team," the Brazilian Football Confederation said.
Neymar, born in 1992, is the player with the most goals in the history of the Brazilian national team with 79 goals after 127 matches. He played an important role for the Brazilian national team at the 2014 World Cup, 2018 and 2022. However, many injuries have prevented him from playing for the Brazilian national team since 2023.
Neymar being called up to the Brazilian national team for the 2026 World Cup by coach Carlo Ancelotti is a big surprise. This striker only played in half of the club's matches in the Brazilian national championship, national cup and Copa Sudamericana this year due to many physical problems.
In the two most recent friendly matches of the Brazilian team that won Panama 6-2 and Egypt 2-1, Neymar could not play. However, coach Ancelotti believes that Neymar will recover, regain his fitness to be able to return to play soon. This strategist emphasized that he will not be hasty in using this veteran striker.
According to the schedule, the Brazilian team will successively meet the Moroccan, Haitian and Scottish teams in the group stage of the 2026 World Cup.
