No wonder there are such huge cuts only in MMA. It is impossible to make such a cut with boxing glove. Such cuts can occur in boxing after head clash or if a bloody bruise explodes. But boxing, imho, is much more traumatic, mainly because there is no pause (like clinch, ground game) from receiving punches. Last UFC was kinda bloody. If not mistaken, Gregory Rodrigues was not the only one to get a huge cut. Song Yadong also got a juicy elbow cut.

But that is nothing to Overeems smile


Some good cuts can be found on
Reddit (just scroll down, and in case link is broken, just google fighters name)
Yup! cuts in boxing were all due to headbutts, but likely boxing fighters will focus more on the head, which may cause head injuries, and concussions to boxers, but with cuts like that, I think it has just less risk with the MMA fights while on boxing boxer could have a trauma with his brain or it can cause brained damage,
That cut was pretty much because of Elbows and Song Yadong has taken it like a man, for me if the fight is not stopped by the doctors there might be a chance that Song Yadong can win this match,
That MMA cut for me is not really life-threatening it is still gruesome, but as you can see Overeem is still smirking although he got a bad lip cut injury, and the thing that surely can cause that head Concoction, was on the boxing part because they focus on hitting the head,
I also expect more cuts in MMA because fighters are allowed to use elbows and they can also kick. The worst cuts I saw in boxing so far were from Badou Jack, Travieso Arce, Vitali Klitschko, and Denis Lebedev.
I remember when UFC goes mainstream and Don King a former top boxing promoter tried to stop it calling MMA a barbarian and very brutal sport. It's been decades now and I cannot remember any deaths from the UFC. While boxing sadly has regular casualties over time. Boxing also has 12 3-minute rounds for a total of 36 minutes compared to UFC's 25 minutes. And boxing's only chance to stop its opponents is by knockouts or technical knockouts where most of the punches are towards the heads. Whereas there are many creative ways in the UFC to stop an opponent.
