Combat sport injuries
There are a few facial injury and bruise morphs, L.I.E. sets, etc. out there, but not so many specifically for injuries one might get from boxing, MMA, and the like. Bloody noses, for example, seem almost impossible to find, and I've yet to find a set with more than a couple.
Likewise, there's nothing out there I've seen for cuts on the cheekbone. FenixPhoenix has some HD Face Wounds products, but those are like sword gashes.
Other possibilities for such a set would be cauliflower ears, broken noses, forehead swelling, and perhaps healing variations for all the bruise materials, showing all the stages of development and recovery. Or even a few presets dedicated to showing a face getting more damaged during a fight, including "between rounds" ones showing wiped-away blood.
I know fighting art is popular, so a good realistic set of such morphs and materials would be as well.
