Britain's former world heavyweight champion Lennox Lewis and actor Will Smith will be pallbearers at Muhammad Ali's funeral on Friday.
London-born Lewis, 50, became undisputed world champion in 1999, while American Smith, 47, played Ali in the 2001 film of the same name.
Three-time heavyweight world champion Ali died last Friday at the age of 74 in hospital in Phoenix, Arizona.
His funeral will be held in his home town of Louisville, Kentucky.
The other pallbearers will be Jerry Ellis, the brother of Jimmy Ellis, Ali's former sparring partner and fellow world heavyweight champion, Ali's cousins John Grady and Jan Wadell, nephew Ibn Ali, former brother-in-law Komawi Ali and family friend John Ramsey.
