Sept 27 (Reuters) - Plans ⁠for Tyson Fury and Anthony ⁠Joshua's long-awaited heavyweight clash were in ‌doubt on Saturday after promoter Dana White said he was unsure whether the fight would go ​ahead.

Fury and Joshua were announced ⁠on Thursday as ⁠opponents for a December 11 showdown at ⁠Cardiff's ‌Principality Stadium, a contest billed as one of the biggest ⁠fights in British boxing history.

However, Fury said ​in ‌a video posted on social media ⁠late on ​Friday that the fight was in jeopardy because Joshua and his promoter, Eddie ⁠Hearn, were trying to withdraw ​from the all-British heavyweight showdown between the former world champions.

White, the UFC president and ⁠head of Zuffa Boxing, told reporters in London on Saturday that he did not know whether the bout would proceed ​as planned.

Asked about a ⁠scheduled press conference in coming days, White ​said he was ‌also uncertain whether it would ​take place.
