Why do sonjay dutt and homicide wear big plasters on shoulders?

Question

pretty much what the title says. ive noticed they both wear something on their shoulders that look like big plasters and they've worn them for a while now.

Answer 1

Homicide wears a bandage of some sort because he hurt his shoulder in ROH doing a flip dive to the outside onto the floor.  

Answer 2

They're sports bandages for any of the wrestlers suffering from muscle strains or tears.The tightness of the bandage supports the muscles / ligaments while wrestling and ensures the "injury" doesn't get any worse.
