A heavy metal bassist ruptured his testicle while playing a gig at the Birmingham O2 Academy, but carried on and finished his set despite the agony.

Otto Schimmelpenninck, 32, was hit by a streamer meant to be fired over his band, Delain, by a cannon.

He told fans on Facebook that his scrotum swelled to the "size of a big grapefruit", but the Dutch musician blames himself for the incident.

He said: "In my enthusiasm I did not pay attention, and happened to be very close when the streamer fired.

"It hit me in my genitals. Although pain was pretty bad, I was merely p**sed off at myself for not paying attention.

"During the next song, the pain got worse and I have the feeling I was bleeding. Pretty soon pain got to the point where I could barely manage to stay conscious, but I did manage to finish the show and even squeeze out some grunts."

Doctors had to remove half a litre of blood from Schimmelpenninck's testicle, reports The Sun.

He said after the operation: "I was close to losing my testicle but chances are good it will be fine."

The moment Schimmelpenninck was struck by the streamers was caught on video.

The accident occurs around the 3.30 mark Delain/Gillian Fuller
