Cycling award lost in middle of riot - flipping clots! (6)
I believe the answer is:
emboli
'clots' is the definition.
(embolus is a kind of clot)
'cycling award lost in middle of riot flipping' is the wordplay.
I cannot really see how this works, but
'award' could be 'mb' (MB is an example) and 'mb' is found within the answer.
'lost' could be 'l' (abbreviation in sporting league tables) and 'l' is found in the answer.
'of' could be 'o' and 'o' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for emboli that I've seen is " Blood clots or air bubbles which cause arterial blockages".)
