Are you sure they are both female?
My suggestion would be to split them until they are spayed/neutered, recovered, and then rebond.
However some people may suggest going back to a small, neutral space and starting again, although personally, with hormones involved, this is not something I would risk.
Also, with rabbits it can be very hard to see wounds and you may only realise in a couple of days when they have scabbed over. Sometimes blowing into the fur all over can show up any wounds, but sometimes not. I would say if they were fighting full on then there are likely to be some wounds so please keep an eye out for them. Those injuries that you have seen need to be bathed, or, if more than a scratch, they need to be seen by a vet.
