Sky Sports apologised to viewers after a gesture which could have been construed as offensive to disabled people by Gerwyn Price during his victory over Jose de Sousa.
Welshman Price was competing in the last 16 of the PDC World Darts Championship at Alexandra Palace when he became frustrated at a failed 180 attempt.
Having hit two consecutive treble 20s, Price's third dart strayed into the single 5. He stuck his tongue behind his bottom lip and held his hands out in front of him in disgust at the dart.
