Gary, Indiana football player missing taxi back (7)
I believe the answer is:
lineker
'gary indiana football' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'player missing taxi back' is the wordplay.
I cannot quite see how this works, but
'player' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
The remaining letters 'linker' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lineker that I've seen before include "Gary -, Engl. footballer" , "Gary --, England footballer" , "Ryegrass, common weed" .)
