Practice boxing (4)

Ross

I believe the answer is:

'practice boxing' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for spar that I've seen before include "Box; various minerals" , "What boxers do" , "Sticks" , "bar" , "Box for practice" .)

I've seen this clue in the Evening Standard, The Star Tribune, the Universal, the Penny Press, The Mirror, the USA Today, the Newsday, the LA Times and The New York Times.
