Cricketer might be this confused (7)
I believe the answer is:
stumped
This clue is a double definition.
'cricketer might be this' is the first definition.
(a player might be stumped in cricket)
'confused' is the second definition.
('stump' can be a synonym of 'confuse')
(Other definitions for stumped that I've seen before include "You'd walk if this" , "Defeated by puzzle" , "Out on the field" , "Baffled" , "Bewildered (on the way out?)" .)
