Boxing-Haye returns with first-round knockout

LONDON, Jan 16 (Reuters) - Former world heavyweight champion David Haye, returning after a three-and-a-half year retirement from the ring, knocked out Australian Mark de Mori in the first round of their non-title bout at the O2 Arena on Saturday. "I felt so cool and calm in there. I don't believe any heavyweight out there could have taken those punches," said the 35-year-old Briton. Haye, who lost his title to Ukraine's Wladimir Klitschko 4-1/2 years ago, plans to take on fellow Briton Anthony Joshua and then wants another shot at the world crown. "I believe that's a fight that could be made later in the year," he said of the projected bout with Joshua. (Writing by Tony Jimenez; Editing by Pritha Sarkar)
