Floored — unseated (6)
I believe the answer is:
thrown
I believe this clue is a double definition.
'floored' is the first definition.
(thesaurus)
'unseated' is the second definition.
(I've seen this before)
(Other definitions for thrown that I've seen before include "Defeated" , "Confused; chucked" , "Having been projected through the air" , "Unseated" , "Hurled, flung" .)
