Rogan had with Dana White on an airplane right after the fight and Dana didn't mention Rousey having any substantial injuries outside of her lip being cut badly. Her mouth was very bloody, but I didn't see any blood coming from her nose in either round, not did her nose appear to have any substantial damage to it. At worse, she might have been dazed if Holm tagged her squarely on the nose, but I highly doubt her nose was broken.
