Cut up, showing concern about five (5)
I believe the answer is:
carve
'cut up' is the definition.
(I know that cut up can be written as carve)
'concern about five' is the wordplay.
'concern' becomes 'care' (synonyms).
'about' is an insertion indicator.
'five' becomes 'V' (Roman numeral).
'care' going around 'v' is 'CARVE'.
'showing' is the link.
(Other definitions for carve that I've seen before include "Attack the turkey" , "Cut meat with sharp knife" , "Cut into pieces" , "Slice (joint)" , "Slice (meat)" .)
