UFC guys get injured way more than boxers?

I know UFC fighters are more susceptible to pre fight injury because of slams,grappling,wrestling,etc..,but recently it is crazy to see what is going on. It feels like 50% of headline fights are canceled due to injury,in some cases both fighters get injured before a fight.I rarely here of boxing matches getting canceled due to injury. Do boxers have more resistance to injury since they start at a very young age?
