Can a team mate give lifting/climbing support?

Question

Can a team mate give lifting/climbing support so that a player can reach the height where goalie or any opponent cannot reach? Is climbing on the goal post allowed?

Answer 1

This is classed as unsporting behaviour. The player doing the lifting, or the player doing the climbing is cautioned for unsporting behaviour, and the opponents are awarded an indirect free kick from where the lift/climb occurred.

• Uses an artificial aid to unfairly assist play – for example, leaning on the shoulders of a teammate to increase height, using an article of clothing to avoid direct contact with the ball, removing the corner flag on a corner kick, hanging on the crossbar.
