The pair are set to throw down in Newcastle next week<\/a> \u2013 a bout Tim is unlikely to attend, with the brothers reportedly still not on speaking terms.<\/p>\n Relations between the siblings soured after Tim\u2019s split from the pair\u2019s manager Glen Jennings, which led to legal action \u2013 a dispute that was seemingly resolved earlier this week. <\/a><\/p>\n Even so, things are still frosty between the brothers.<\/p>\n \u201cI\u2019ve been trying not to think about it too much during fight camp,\u201d Nikita told Fox Sports Australia.<\/p>\n \u201cI always try and think in a positive way about things.\u201d<\/p>\n Nikita Tszyu (L) and Oscar Diaz (R) face off during an open workout at Bondi Boxing Club on April 30, 2026 in Sydney, Australia.

Fighting is a very personal thing to me.<\/p>\n \u201cI get into the headspace where I need to think I\u2019m taking someone\u2019s life and be ready to do that.<\/p>\n \u201cI can\u2019t do that with a family member.<\/p>\n \u201cI can\u2019t put that stress on my family as well.\u201d <\/p>\n As revealed last week, Tim Tszyu will throw down against Errol Spence Jr. on Sunday, July 26 in Australia \u2013 doing so under a new-look team led by his third coach in six months, Hall of Famer Jeff Fenech. <\/p>\n Nikita says that news really did surprise him.<\/p>\n Brothers Tim and Nikita Tszyu are hunting boxing glory.
