Billy Joe Saunders and Kell Brook have been sparring with one another as they start training camps for fights at the end of this year.
The WBO super-middleweight champion and former IBF welterweight champion are both hoping to be in notable bouts in the coming months after missing out on valuble time because of the pandemic.
Brook is closing in on a deal to challenge Terence Crawford for his WBO welterweight title next.
The Sheffield man has been training through lockdown as he intends to return to 147lbs once more.
Saunders meanwhile is targeting Callum Smith or Demetrius Andrade.
However it is as yet unclear whether either of these two bouts will be able to come to fruition.
“Good eight rounds banked this morning,” Brook posted on social media on Monday.
“First open spar ever done with the champ Billy Joe Saunders.
“Iron sharpens iron, champ camp.”
