Rick takes run in the country (6)
I believe the answer is:
'rick' is the definition.
(I know that rick can be written as sprain)
'run in the country' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'in the' means one lot of letters goes inside another.
'country' becomes 'Spain' (Spain is an example).
'r' put within 'spain' is 'SPRAIN'.
'takes' acts as a link.
(Other definitions for sprain that I've seen before include "Injury to ligaments" , "Wrench or twist" , "Strain (eg, ankle)" , "Injure joint by wrenching it violently" , "Turn" .)
