Who would be ducking who in this scenario?

[King of Sting]

Two cash cows of the industry about to get it on. However, fighter A is demanding fighter B to wear "pillow gloves" while Fighter B has made millions out of annihilating opponents with horse-hair padded gloves.

If Fighter A decides to not fight due to fighter B not meeting his demands is he ducking or is Fighter B ducking for not agreeing to what fighter A wants?

Please vote on the poll. Thank you.
