Charlatan showed sign of injury and shuffled along (8)
I believe the answer is:
Here is my best explanation:
'shuffled along' is the definition.
'charlatan showed sign of injury' is the wordplay.
'charlatan' becomes 'sham'.
'showed sign of injury' becomes 'bled'.
'and' acts as a link.
(Another definition for shambled that I've seen is "walked unsteadily".)
