Crossword Genius

Put "unprofessional" (3)

Ross

I believe the answer is:

This clue is a double definition.

'put' is the first definition.
('lay' can be a synonym of 'put')

'unprofessional' is the second definition.
(I've seen this before)

(Other definitions for lay that I've seen before include "Not professional", "in which hens regularly produce eggs?", "Song-ballad", "Air", "Of bird, produce egg".)

I've seen this clue in Evening Standard.
