Bump from slow boat damaged creel (8)
I believe the answer is:
tubercle
'bump' is the definition.
(thesaurus)
'slow boat damaged creel' is the wordplay.
'slow boat' becomes 'tub' (I've seen this before).
'damaged' is an anagram indicator.
'creel' anagrammed gives 'ercle'.
'tub'+'ercle'='TUBERCLE'
'from' is the link.
(Other definitions for tubercle that I've seen before include "Small rounded swelling characteristic of TB" , "Small swelling, nodule" .)
