In short
The answer first
A player may legally shield the ball by placing their body between an opponent and the ball while the ball remains within playing distance and arms are not used illegally. Impeding occurs when a player moves into an opponent's path to obstruct or slow them when the ball is not within playing distance. Contact and the nature of the action affect the restart.
Key takeaways
Legal shielding requires the ball to be within playing distance.
The opponent is allowed to challenge fairly for the ball.
Holding, pushing or charging illegally can create a separate direct-free-kick offence.
Impeding without contact and impeding with contact have different restart consequences.
Strength alone does not make body positioning illegal.
Position is not possession
A player does not need to touch the ball continuously to shield it, but they must be close enough to play it. Using the body to protect that reachable ball is a normal part of football.
The opponent can try to move around and challenge fairly. The shielding player cannot convert the action into holding or pushing.
When the ball is too far away
If a player steps across an opponent solely to block their route while the ball is not within playing distance, the referee may judge impeding. The presence or absence of contact affects whether the restart is indirect or direct under Law 12.
This is especially relevant during runs towards a loose ball, where a defender may try to let the ball travel out of play.
Watch distance and arms
On a replay, check how far the ball is from the player and whether they could reasonably play it. Then watch the use of arms, hips and upper body.
A strong stance can be legal. An action that holds or knocks an opponent away may not be, even if commentators casually call both shielding.
