How strong is the cartilage graft 90 days after revision Rhinoplasty?

I had revision w/ bone shaving and ear cartilage graft on the tip. But last week, at 90 days post op, i got hit on the nose while playing volleyball. It's not a hard hit, but it was painful and there's little blood when I put a rolled tissue up my nose. The pain did not last too long. I can't really see if there's some change in shape as it swelled a bit too. Did I do some permanent damage? Does the graft ever fully attach to the nose? How strong is it 90 days post op? Thanks!
