Former British heavyweight champion Frank Bruno has been treated for pneumonia.
The 57-year-olds agent said he needs “a few weeks’ rest” after being admitted to hospital. Bruno was ringside for Chris Eubank Jr's victory over James DeGale in London on 23 February.
Bruno won the WBC heavyweight title at the fourth attempt when he beat American Oliver McCall at Wembley in September 1995.
Last week marked the 30th anniversary of Bruno's most famous fight, when he lost to Mike Tyson in 1989.
