Bloke on course that's collapsed (4,4)

'collapsed' is the definition.
(to fall away is to collapse or crumble)

'bloke on course' is the wordplay.
I cannot quite see how this works, but
'bloke' could be 'fella' (non-standard spelling of 'fellow') and 'fella' is found in the answer.
'course' could be 'way' (way is a kind of course) and 'way' is located in the answer.
No letters remain.
This explanation may well be incorrect...

'that's' is the link.
