Block
A front-row player jumping at the net with hands up to stop the other team's attack. You can block alone or next to a teammate. A block that sends the ball straight down on their side is a stuff. A block that only slows the ball still helps, because your defenders get a chance to dig it. Reaching over the net is legal once the hitter has swung, as long as you do not touch the ball before they attack. A block does not count as one of your three team hits. Back-row players, including the libero, are not allowed to block.
Example
The middle blocker reads the set and the outside blocker closes the gap. Together they send the ball straight down on the hitter's side of the net.
Frequently Asked Questions
Does a block count as a touch in volleyball?
No. Under FIVB and NCAA rules, a block is not one of your three contacts. Your team still has three hits after the block, and the player who just blocked can take the first of those.
Can back-row players block in volleyball?
No. Only front-row players can block. If a back-row player or the libero reaches over the net as part of a block, it is a fault and the other team gets the point.
