Stokes has taken a catch right on the boundary edge. They are checking if he was in contact with the ad cushions. Seemed fine on first instance. Let’s see what the slow-mos say.. The reverse angle shows his left foot outside the boundary rope as he releases the ball. That should be a SIX.
Unadkat to Shreyas Iyer, SIX, matter of seconds. Had Stokes thrown the ball up a second earlier he would have had his man. Nonetheless, it is a fifty for Iyer. It is the slower ball again and Iyer mows it towards deep mid-wicket, not as clean as the last one and hence Stokes was in action. He jumps up and takes the catch but as he was landing, he throws the ball up but the left foot had already landed outside the rope
Here is the clip of that video:
