Batsman could face this serious injury (3,5)
I believe the answer is:
leg break
This could be a double definition.
'batsman could face this serious' is the first definition.
The definition suggests a singular noun which matches the answer.
'injury' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for leg break that I've seen before include "Type of spin at cricket" , "Switch from on to off" , "Sort of spin" , "Cricket delivery" , "injury" .)
