Hockey team’s legs (6)
I believe the answer is:
eleven
This could be a double definition.
'hockey team's' is the first definition.
'eleven' can be an answer for 'team's' (eleven is a kind of team). I'm unsure of the 'hockey' bit.
'legs' is the second definition.
(eleven is 'legs eleven' in the game bingo)
Can you help me to learn more?
(Other definitions for eleven that I've seen before include "Time for morning coffee" , "Number in a cricket team" , "Number on a soccer team" , "Football team; number" , "'Legs' bingo number" .)
