Queen featured in silly sketch (5)
I believe the answer is:
draft
'sketch' is the definition.
(draft is a kind of sketch)
'queen featured in silly' is the wordplay.
'queen' becomes 'r' (r is abbreviation regina. e.g. in ER ).
'featured in' indicates putting letters inside.
'silly' becomes 'daft' (I've seen this before).
'r' placed inside 'daft' is 'DRAFT'.
(Other definitions for draft that I've seen before include "Sketch; money order" , "sketch, perhaps" , "Send" , "Preliminary outline" , "Bank payment order" .)
