Former two-time heavyweight champion Anthony Joshua has been ranked No.1 by The Ring magazine in the latest rankings while rival Tyson Fury misses out after he gave up his belt when he announced he was retired in August.
Joshua suffered his second consecutive defeat to Oleksandr Usyk in September, which has put him out of the heavyweight world title picture for the first time in several years.
Meanwhile, Fury declared he had retired from the sport after his successful title defence against Dillian Whyte, but has now announced he will return on December in Cardiff.
