Run out with elbow

There was a contentious incident in a recent Test Match involving Pakistan and England when Yasir Shah was run out by a combination of Chris Woakes' arm and Jonny Bairstow’s elbow.
Sarfraz Ahmed called Yasir Shah for a second run but the No. 8 was always going to struggle to make his ground. He put in a leap at the end of the run, the third umpire was called into play, and he was given out – despite the ball never having actually touched the stumps. It was a fair dismissal as the ball was in Bairstow’s hands when his elbow knocked the stumps down.
As MCC’s Law 29 states, as long as it is the arm being used of the hand which has the ball, it would be a run out Had Bairstow knocked the stumps over with his legs or any other part of his body with the ball in his hands, it would not have been out.
