Rocker Axl Rose is nursing severe bruising to his left leg after a wild weekend in Russia.
The Welcome to the Jungle singer has taken to Twitter.com to show fans a picture of his suspected haematoma, which occurs when blood pools under the skin.
He captioned the shot, "Can U say HemaToma?!"
It is believed the Guns N' Roses star was hurt after partying with his bandmates following shows in Moscow on Friday and Saturday (11-12May12).
A source tells Britain's The Sun, "Axl needed attention for a nasty leg injury after a suspected fall."
