Yes, but most the majority of the time they knee the ball.
As long as the returner never steps out of the endzone with the ball than it is a touchback, because it would be just like taking a knee. But if he was ever outside of the endzone with the ball and gets tackled in the endzone it is a safety.
Brian Westbrook of the Eagles to run the clock
On September 6, 2014 The Wisconsin Badgers scored a safety against the Western Illinois Leathernecks on the opening kickoff. Only 1 second had elapsed from the time clock. The Western Illinois receiver received the ball in the end zone, stepped out then back in, and took a knee resulting in a 2 - 0 Wisconsin lead.
Only if you remove their knee to do so.
That is the correct spelling of "knell" (clock tolling sound). The similar word is "kneel" (to go down on a knee).
Wisconsin Badgers on 6 September 2014 scored a safety on the opening kickoff with 1 second off the game clock. The Western Illinois running back Kyle Hammonds bobbled the return and allowed the ball to bounce out of the end zone to the 1-yard line. He then brought ball back into the end zone and took a knee for a safety.
Yes, when the QB takes a knee or slides he is telling everyone that he does not intend to advance the ball any further. Any player in possession of the ball may do this without penalty.An example would be on a kickoff that travels into the end zone. The returner can catch the ball and go down on one knee to indicate he does not intend to advance the ball. In this instance, the ball is placed on the 20 yard line and the receiving team has possession on first down.Another example would be late in a game when a defensive player makes an interception with the offensive team behind and driving for the go ahead score. Instead of running with the ball he may go down to the ground to end the play to avoid being hit and possibly fumbling the ball back to the offensive team.
no, it is not a dead ball (otherwise you wouldn't be able to pick up a ball off of the ground on a kickoff or punt). The ball carrier has to touch a knee or elbow to be ruled down.
If his knee touches inbounds, he is considered tackled in the field of play, regardless if the the ball ends up out of bounds. The clock will continue to run
they can. but it would be called a safety and the opposing team would gain 2 points and the ball back by kickoff. because forward progress was made, it is the same as if the quarterback was sacked in the teams endzone. the receiving player who would do this would be quickly lynched by his own fans. There is a reason why this has not been done.
Yes, and knee extension would be when the knee is straight.
