Fouls (3.C): It is the responsibility of all players to avoid contact in every way possible.
Avoid contact in every way reasonably possible, while still playing ultimate. Some contact is inevitable, but players have an affirmative obligation to make reasonable efforts to avoid contact.
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 This rule is not superseded by any other rule.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.
Dangerous play occurring when or immediately after the disc is in the air is treated as a receiving foul if either player involved is attempting a play on the disc. However, the calling player may elect to treat the dangerous play as a general foul, if the player determines that the dangerous play was unrelated to the overall play that decided the outcome of the action.
For example, if a third player appears and grabs the disc far before it reaches the two involved players, or if the disc is thrown to the opposite side of the field, the involved players will not be attempting a play on the disc. However, if multiple players accumulate under a floating disc, one player's dangerous play will be treated as a receiving foul, even if a third player happens to make a successful play on the disc, as the players under the disc were attempting a play on the disc. The calling player would have discretion to deem the third player's play so independent and removed from the involved players that the calling player wishes to treat the dangerous play as a general foul rather than a receiving foul. In general, a calling player's decision that a dangerous play was unrelated to the overall play will be based on the dangerous play being removed in significant distance or time from the overall play. By way of further example, even a dangerous play committed against a player unaware of the approaching disc will be treated as a receiving foul, where the offending player was attempting to make a play on the disc, giving the benefit of the doubt that the calling player could potentially have become aware of the approaching disc, had the offending player made a safe play. In this instance, the calling player could determine that it would not have been possible to become aware of the disc such that the outcome of the play would have changed and therefore elect to treat the dangerous play as a general foul.
Dangerous play is treated as a general foul only if it occurs when the disc is not in the air, occurs far away from the disc, when the disc is obviously uncatchable, or when the calling player has elected such treatment under 17.I.1.b.2. In this situation, the calling player determines whether the play was affected, under the standard enunciated in this rule and its annotations.
A disc is obviously uncatchable only when it hits the ground before a catch could possibly be made, is out-of-bounds with no possibility of an in-bounds completion, or otherwise presents no opportunity for a catch (whether initial or subsequent efforts), giving every benefit of the doubt to the calling player. In determining whether a dangerous play affected the play under 17.I.1.b.3, the calling player should broadly consider the entire play, including any approach taken by the offending player immediately before the dangerous play. A good rule of thumb is to look to the last time when a player could have still changed their actions and actively avoided a dangerous outcome but did not (the "point of no return") through the time immediately after resolution of the play and broadly consider whether the outcome of the play could possibly have been different, had the offending player taken a safe approach. Even a player's awareness of the presence of the offending player can affect the play.
