I believe the answer is:

stand-off

I'm a little stuck... Click here to teach me more about this clue!

'rugby player' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for stand-off that I've seen before include "Rugby player - deadlock - keep at a distance" , "Deadlock (in match)" , "Impasse" , "Deadlock between two matched opponents" , "Rugby halfback" .)

I've seen this clue in The Telegraph.
