Boxer Mike ____ (5)
I believe the answer is:
tyson
'boxer mike' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tyson that I've seen before include "Mike --, US boxer" , "26 4 [RING MASTER]" , "Youngest ever undisputed world heavyweight boxing champion, b, 1966" , "US world heavyweight boxing champion, b.1966 -- English fast bowler, d. 2015" , "Undisputed world heavyweight champion, 1987" .)
