Anthony Joshua declared there is "no place to hide" for Tyson Fury after the first official offer to stage their heavyweight unification fight was lodged.

Promoter Eddie Hearn last week revealed he plans to present "three or four offers" to the respective teams of Joshua and Fury for an eagerly awaited unification bout.

Negotiations over a blockbuster showdown between the British duo have been ongoing for several months, with Hearn revealing a two-fight deal has been signed.

WBA, WBO and IBF champion Joshua has provided a positive update as he eyes Fury's WBC belt.

"Positive news this evening! I'm lacing up my running boots rn [sic]!!!" Joshua posted on social media.

"@258MGT and @Matchroomboxing have received the first official offer to host the Undisputed Heavyweight Championship Of The WORLD! I will be victorious God Willing!

"No place to hide now! IM [sic] COMING."

John Fury - Tyson's father – recently expressed his concerns over the ongoing negotiations in an interview with Boxing Social, citing the financial difficulties due to the impact of the coronavirus pandemic.

Hearn, Joshua's promoter, tweeted on Sunday: "Busy day today and a long night ahead!"
