Crossword Genius

Call used in boxing (4)

Ross

I believe the answer is:

ring

I believe this is a double definition.

'call' is the first definition.
(telephone call)

'boxing' is the second definition.
(thesaurus)

'used in' acts as a link.

(Other definitions for ring that I've seen before include "Buzz" , "Chime" , "sign of union?" , "Circular band; call" , "Make phone call" .)

I've seen this clue in The Globe and Mail.
