Progress is available (5)
I believe the answer is:
going
I believe this clue is a double definition.
'progress' is the first definition.
(I've seen this before)
'available' is the second definition.
(I've seen this before)
'is' acts as a link.
(Other definitions for going that I've seen before include "State of turf" , "Progress" , "Surface condition (that may get tough!)" , "Running; leaving" , "Available" .)
