Blood sport "edgier, wild" (8)
I believe the answer is:
pedigree
'blood' is the definition.
(I know that blood can be written as pedigree)
'sport edgier wild' is the wordplay.
'sport' becomes 'PE' (physical education).
'wild' indicates anagramming the letters.
'edgier' is an anagram of 'digree'.
'pe'+'digree'='PEDIGREE'
(Other definitions for pedigree that I've seen before include "(Distinguished) lineage" , "Lineage of purebred animal" , "Pure lineage" , "Distinguished line of ancestors" , "Breeding; descent" .)
