Awkward redhead may be stuck (7)
I believe the answer is:
adhered
'be stuck' is the definition.
(I've seen this before)
'awkward redhead' is the wordplay.
'awkward' is an anagram indicator.
'redhead' with letters rearranged gives 'ADHERED'.
'may' acts as a link.
(Other definitions for adhered that I've seen before include "Stuck to, remained loyal" , "Stuck - redhead (anag)" , "Showed sticking power" , "Stuck (to something)" , "Stuck; glued" .)
