A tighthead prop is one of the three players at the front of the scrum.

They stand on the right-hand side of the hooker.

As they take most of the impact in the scrum, a prop should have plenty of strength in their upper body.

This is the area of the body where all the power is created for the big push.

Most props are quite short and squat - but don't say that to their faces!

Props also love getting stuck into tackles and you will often find them at the bottom of a rucks or a maul.
