Dangerous Play. Actions demonstrating reckless disregard for the safety of or posing a significant risk of injury to fellow players, or other dangerously aggressive behavior are considered "dangerous play" and are treated as a foul. The proper call in such circumstances is "dangerous play" and play stops. This rule is not superseded by any other rule.
The following are non-exhaustive examples of dangerous play:
- significantly colliding with a mostly stationary opponent,
- jumping into a group of mostly stationary players,
- diving around or through a player that results in contact with a player's back or legs,
- running without looking when there is a likelihood of other players occupying the space into which the player is traveling,
- jumping or otherwise leaving the ground where it is likely that a significant collision will result,
- wild or uncontrolled throwing motions,
- initiating contact with a player's head,
- initiating contact with an airborne player's lower body that prevents them from landing on their feet, and
- jumping right in front of a sprinting player in a manner where contact is unavoidable
Resolution. If uncontested, a call of "dangerous play" is resolved as an analogous foul (e.g., if the call occurred while or immediately after the calling player was making a play on a disc in the air, it is treated as a Receiving Foul (17.I.4.b)). A player called for dangerous play may contest the call if they believe the call was incorrect (17.B).
Dangerous play between a thrower and marker is treated as a throwing foul that affected the play, regardless of whether or when the disc is released or when contact occurs, unless the calling player determines otherwise.
