Sopranos actor Vincent Pastore has pulled out of US reality TV show Dancing With The Stars.

The 60-year-old realised that the competition was too physically demanding after one week of training. Pastore's place will now be filled by another competitor.

"When I initially committed to joining Dancing With The Stars I didn't realise just how physically demanding it would be for me," Pastore told WENN. "Unable to put forth my best effort, I felt it appropriate to step aside and give someone else the opportunity."

Executive producer Conrad Green added: "Dancing With The Stars is physically demanding and it pays to know your limits. We respect his decision."
