No striking evidence of injury? (4)
I believe the answer is:
scab
'evidence of injury?' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scab that I've seen before include "Ignorer of strike" , "Crust forming over wound" , "One continuing to work" , "work when others are out" , "that blocks cut" .)
