World snooker champion Mark Williams may miss the Champions Cup in Brighton on August 27.
The world number one was bitten several times on his left hand by his pet Rottweiler Megan as he attempted to feed it.
The anxious 25-year-old is now seeking medical advice to see how long he will be out of action.
Williams said: "There was quite a bit of blood. I tried to practice in the afternoon and I couldn't hold the cue it was just so painful.
"It's a real worry with the new season coming up so I just hope that it's nothing too serious."
