An Australian rugby league player has finally found the cause of his persistent headaches. Ben Czislowski had suffered shooting pains in his head since April when he got engaged in a head clash with the player of opposite team, but it was only last week that doctors discovered a tooth buried in his head just above the eye.

After the incident, Czislowski had his head wound stitched up without doctors noticing the tooth.

"I can laugh about it now but the doctor told me it could have been serious," the 24-year-old, who now keeps the tooth on his bedside table, told the AP.

Tweed Heads forward Matt Austin, who was apparently not wearing a mouthguard that day, lost several teeth in the incident.
