True. According to the rules, if a player is injured during play and calls an injury stoppage, they must choose either to be substituted or to charge their own team with a Time-Out, if their team has no time-outs remaining. This rule ensures that the game can continue smoothly while also addressing the needs of the injured player.

In beach Ultimate, the rules for time-outs generally follow the same guidelines as in other forms of Ultimate, but it's important to confirm any specific adaptations for beach play from the tournament or league rules. Typically, during a time-out in Ultimate: 1. A player must clearly signal a time-out by forming a "T" with their hands or with one hand and the disc, while also verbally calling "time-out" to ensure that the opposition is aware of the stoppage. 2. The duration of the time-out and the actions following it, such as the time allowed for players to set up and resume play, are strictly timed. For instance, after a time-out is called, players have a set period (usually around 75 seconds) to resume their positions and prepare for the continuation of the game. 3. Specific warnings are given at intervals (45 seconds, 60 seconds, and 75 seconds) to indicate the remaining time to the teams. 4. If a team attempts to call a time-out when none are remaining, the play is stopped, and specific penalties, such as adjustments to the stall count, are applied. For beach Ultimate, it's crucial to check if there are any modifications to these rules, such as reduced time for time-outs due to the faster pace and shorter game durations typical of beach formats.

In Ultimate frisbee, non-players are generally not allowed to prompt players on the field to call for a time-out. The rules emphasize that it is the responsibility of the players themselves to make calls, including time-outs. Non-players can only provide advice or intervene in specific situations when explicitly requested by a player involved in the game. For instance, non-players may assist as translators during a stoppage to facilitate communication but should not influence the decision-making process regarding game plays such as calling time-outs.

True. According to the rules of Ultimate, if the disc was in the air when the injury stoppage was called, play continues until either a player establishes possession, or the disc hits the ground. If the injury is not the result of a foul by an opponent, the completion or turnover stands, and play restarts there after the stoppage.

True. According to the rules of Ultimate, a team-mate, coach, or designated official should actively alert players to any condition that endangers players. This is in line with the emphasis on safety within the sport.

False. According to the rules of Ultimate, if the injured player had established possession of the disc and then dropped the disc due to the injury, that player retains possession of the disc (19.1.3). The reference provided in the question (19.1.4) does not match the information given in the sources, but the correct rule is found in source 19.1.3.

True. According to the rules of Ultimate, any player, coach, or designated official can alert players to any condition that endangers players. This is to ensure the safety of all participants during the game.

In the scenario where a player gets fouled and calls an injury as a result of the foul, the rules of Ultimate provide specific options for the injured player. According to the rules, if the injury was caused by an opponent, the player has the option to either stay in the game or to be substituted without any need to charge their own team with a time-out. This is outlined in the rules regarding safety stoppages. However, if the injury was not caused by an opponent, then the player must choose either to be substituted or to charge their own team with a time-out, as per the rules. Charging their own team with a time-out means that a time-out is deducted from those allowed for that half, but the team does not get the opportunity to discuss tactics or have a break as per a standard 75-second time-out. In summary, if the injury is caused by an opponent, the player may choose to stay or be substituted without affecting their team's time-outs. If the injury was not caused by an opponent, the player must either be substituted or charge their team with a time-out.

False. According to the rules of Ultimate, if a player is injured as a result of a foul caused by an opponent, they have the option to either stay in the game or be substituted. They are not required to charge their own team with a time-out in this situation. This is outlined in the rules regarding safety stoppages.

According to the rules of Ultimate, if an injury stoppage is called while the disc is in the air, play should continue until a player establishes possession or the disc hits the ground. If the injury is not caused by a foul from an opponent, then the outcome of the play (completion or turnover) stands. After addressing the injury stoppage, play would restart from the point of the turnover.

True. According to the rules, any player, coach, or designated official can alert players to any condition that endangers players. This is reflected in the rules of Ultimate, specifically in the section regarding safety stoppages.

False. According to the rules of Ultimate, if a player is injured as a result of a foul caused by an opponent, they have the option to either stay in the game or be substituted without having to charge their own team with a time-out. This is outlined in the rules, which state that if the injury was caused by an opponent, the player may choose to stay or to be substituted (source_reference). If the injury was not caused by an opponent, then the player must choose either to be substituted or to charge their own team with a time-out (source_reference). Therefore, the statement that a player must choose either to be substituted or to charge their own team with a time-out after being fouled is incorrect, as it does not account for the situation where the injury is caused by an opponent.

True. According to the rules of Ultimate, if a player has established possession of the disc and then drops the disc due to an injury, that player retains possession of the disc. This is outlined in the rules regarding safety stoppages.

False. According to the rules of Ultimate, during an injury stoppage, players are not allowed to move to establish a stack before the substitute comes on the field. The rules specify that during any stoppage, opposing players may agree to slightly adjust their locations to avoid potential picks (source_reference 8), but there is no rule that specifically allows players to move to establish a stack during an injury stoppage. When a player is substituted after an injury, the substitute takes on the full state (location, possession, stall count, etc.) of the player they are substituting (source_reference 14). This implies that players should maintain their positions until play is resumed.

If the thrower calls a time-out when there are no time-outs left, the outcome depends on the state of play when the time-out is called: 1. If the thrower calls a time-out during a stoppage in play, the call has no effect since the team has no time-outs remaining. 2. If the thrower calls a time-out while play is live (the disc is in play), play is stopped. The marker must then add two seconds to the stall count they would have restarted play on before restarting play with a check. If this addition results in a stall count of ten or above, it is considered a "stall-out" and results in a turnover. To call a time-out, the player must form a "T" with their hands, or with one hand and the disc, and should audibly call "time-out" to the opposition players.
