Toward wicket, one lacking faith died down (7)
I believe the answer is:
infield
'toward wicket' is the definition.
(part of cricket pitch near the stumps)
I don't understand the remainder of the clue.
(Other definitions for infield that I've seen before include "From part of playing area" , "close to batsman?" , "Area inside racetrack" , "down from fence?" .)
