Unless you shove yourself? Yes - it can happen and some of them are very good at it. Forwards especially spend ages practising throwing themselves to the ground. The only clue you get is the speed and timing with which it happens. Sometimes they just seem to go down too quickly.
To judge whether it's a shove you need to see the nuances of the moves, how the alleged shiver has planted his feet, how his weight changes, how the one being shoved changes body shape under the impulse, these are all difficult to determine through a television screen. I'm not saying that this definitely wasn't a foul, by the way, just that what you see on TV is not necessarily what actually happened.
Anyway, back to the game
