Quarterback's throw (4)
I believe the answer is:
pass
'quarterback's throw' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pass that I've seen before include "Hand over < identity card" , "Go by; succeed in (an exam)" , "exam grade ..." , "Exceed; mountain route" , "Gesture to hypnotise" .)
