Kindelan had announced he would hang up his gloves last August after clinching his second straight Olympic lightweight gold medal in Athens.
At the time, the 32-year-old said he wanted to pursue coaching and spend more time with his family.
But various state-run news agencies reported Saturday that the boxing great said he decided to continue competing to achieve more titles.
Speaking from the eastern city of Holguin, where he was spending the holidays with his family, Kindelan said he plans to compete in a world competition in Moscow in June.
\"I am motivated, and without worries about my future plans,\" he said. \"I am going to increase my training.\"
(Which means trouble for Khan at the Worlds) I wonder what Amir will think of the news?
