Former Brighton midfielder Enock Mwepu is hospitalized in Zambia after unwell, according to his former club.
The 25-year-old was forced to retire football in October due to an inherited heart condition.
Reporting from his native Zambia said he suffered a suspected heart attack on Sunday while driving and another motorist saw him fall from his car.
“Enock was ill in Zambia and is currently undergoing precautionary checks,” a Brighton spokesperson said.
“Our medical team is in communication with the hospital to help if needed.
“The club would like to thank the many supporters for their messages and support.”
Announcing his retirement last year, Brighton said Mwepu would be at “extremely high risk of suffering a life-threatening cardiac event” if he continued playing.
He had fallen ill during a trip with the Zambian national team to Mali in September, unable to train after arriving in West Africa and spent four days in hospital.
Mwepu had tests on his return to England and Brighton said the results meant the “only option” was for him to retire.
He joined Brighton from Red Bull Salzburg on a four-year £18m deal in July 2021, scoring three goals in 27 appearances for the club.
