Short pitch: Battle scar?

I’m not in the mood for much typing tonight. I returned from cricket with a sore thumb.

The question for you is, did I sustain this minor injury:

A: hitting my thumb with a mallet when setting up the stumps before the match;

B: fending off a bouncer;

C: shutting the car door on it when hurrying back to the house for my son’s spikes that he had left behind;

D: rolling the pitch covers over it when positioning them after the match.
