Paris Saint-Germain forward Neymar is a doubt for Brazil’s opening 2022 World Cup qualifier against Bolivia because of a back problem, the Selecao team’s doctor Rodrigo Lasmar said on Wednesday. The 28-year-old was earlier forced to leave a training session at Brazil’s Granja Comary base in Teresopolis, near Rio de Janeiro, to undergo physiotherapy. “Neymar felt pain in the lumbar region during the warm-up of today’s training … and was taken off and examined,” Lasmar said in a video sent to reporters.
