Heard Matt worship bullfighter (7)
I believe the answer is:
matador
'heard matt worship bullfighter' is the definition.
'matador' can be an answer for 'bullfighter' (synonyms). I am unsure of the 'heard matt worship' bit.
'matt worship bullfighter' is the wordplay.
'matt' becomes 'mat' (synonyms).
'worship bullfighter' becomes 'ador' (I can't justify this - if you can you should believe this answer much more).
