Ailing Ryan O'Neal will appear at the Oscars -- Despite suffering from leukemia and recent reports of worsening health, the actor will present at the Academy Awards

Despite recent reports that he is gravely ill, actor Ryan O’Neal is still set to be a presenter at the Academy Awards Sunday night (March 24), accompanied by his ”Love Story” costar Ali MacGraw, Reuters reported. O’Neal, who is suffering from chronic leukemia, is weighing whether to undergo a bone marrow transplant, according to People magazine.
