Brazilian midfielder Oscar was rushed to a hospital in São Paulo earlier today after collapsing during a routine fitness test.
Medical reports indicate that the 33-year-old suffered a heart-related issue and is currently under close observation.
Doctors have reportedly advised further tests to determine the extent of the condition, with early indications suggesting that his playing career may be at risk.
No official statement has been released by Oscar or his representatives, but sources close to the player describe the situation as “serious but stable.”
Oscar, who currently plays in Brazil after spells in Europe and China, is best known for his time at Chelsea, where he won the Premier League and Europa League titles.
