What constitutes attempting to hurdle an opponent?

Attempting to hurdle an opponent is defined specifically by the action of jumping over them with both feet or knees, which involves making contact with the ground either during the jump or upon landing. This definition underscores the action of actively trying to clear the opponent as a way to bypass them while maintaining play.

In this context, jumping with both feet or knees over an opponent signifies an effort to navigate around them by leaping, which is the essence of hurdling. Hurdling is often seen in situations where a player is faced with an opponent who is either prone or kneeling, and this manner of movement is typically deemed a physical maneuver to avoid potential contact while advancing the play.

The other options highlight actions that do not fit the criteria for hurdling. For instance, jumping over a lying opponent does not capture the essence of a hurdle in the context of the rules as it lacks the dual-foot or knee action in relation to ground contact. Running around or crawling under an opponent also does not represent the act of hurdling, as both involve evasion without the jumping or leaping components necessary to be considered a hurdle.
