I second Mikey on separating them until he is completely healed. I had a pair (that had been living together for 5 months) that got into a fight, I took them to the vet, and then they seemed ok (actually better than before) after the fight, but then a week later got into a more serious fight where one needed a suture on her lip. Needless to say I felt awful, but was thankful someone was home when it started, otherwise it could have been much much worse.
If you keep up with the pre-bonding stuff and keep them side by side while they are separated they won’t forget about each other. Sounds like they are still sorting things out, so def make sure to supervise them more again, and wait till the bite wound is healed before continuing sessions.
I understand the feeling of not wanting to lose progress, but believe me that it will be a stronger bond if you slow down and make sure each bunny is healthy and safe throughout the process. (I can imagine a situation where your girl is dominant, and your boy tolerates it just because is injured..but then he heals up and all of the sudden he wants to be dominant again…. then you have more fights…).
