Sign of injury from run in country (6)
I believe the answer is:
sprain
'sign of injury' is the definition.
(sprain is a type of injury)
'run in country' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'in' is an insertion indicator.
'country' becomes 'spain' (Spain is an example).
'r' placed into 'spain' is 'SPRAIN'.
'from' acts as a link.
(Other definitions for sprain that I've seen before include "Rick" , "Wrench, dislocate" , "Slight muscle injury, eg to ankle" , "Wrench (limb)" , "Wrench (an ankle) 6)" .)
