Tim Tszyu understandably was asked about rematches with Sebastian Fundora and Bakhram Murtazaliev during a Zoom interview with a few reporters this week. The former WBO junior middleweight champion made it perfectly clear, though, that he is more interested in his “unfinished business” with a former unified welterweight titleholder. If the Australian contender can end his two-fight losing streak Sunday afternoon against American Joey Spencer, Tszyu seems most interested in fighting Keith Thurman next.
