Arrange cups with king’s sporting gear (5)
I believe the answer is:
Here is my best explanation:
'sporting gear' is the definition.
'arrange cups with king's' is the subsidiary indication.
'arrange' is an anagram indicator.
'with' is an insertion indicator.
'king' becomes 'k'.
'cups' with letters rearranged gives 'pucs'.
'pucs' going around 'k' is 'pucks'.
