小蜘蛛进球为何有效？IFAB规则：疑似手球的巴埃纳并非进球者（小蜘蛛进球为何被判有效？IFAB：巴埃纳疑似手球但非进球者）

Reviewing handball rules

I'm recalling the changes around handball rules over the seasons. In 2020/21, IFAB clarified that accidental handballs leading to a goal shouldn't be punished unless the scorer was involved. But back in 2019/20, any accidental handball by an attacker leading to a goal or scoring opportunity was already considered an offense. Then, in 2021/22, they relaxed this to only apply when a player scored immediately after such a handball. I need to ensure my facts are accurate regarding these updates.Clarifying accidental handball rules

I’m reviewing the rules surrounding accidental handball leading to a goal. Essentially, if a player scores directly from their hand or arm—even accidentally—it counts as an offense. In March 2021, IFAB clarified that accidental handballs in the buildup no longer count as offenses unless they immediately precede a goal by the scorer. The 2021/22 law specifies that it’s an offense if a player scores right after the ball touches their hand or arm, even accidentally. I need to ensure I’m clear on these nuances!Clarifying handball rules

I realized that the updated rules don’t penalize a teammate’s accidental handball; only the scorer's accidental handball counts as an offense. For example, if Baena handled the ball accidentally and Alvarez scored, it’s valid under the rules. The user's mention of "疑似手球的巴埃纳并非进球者" highlights the need for clarity on IFAB's position that only the scorer's handball is penalized. If a teammate handles the ball deliberately to gain an advantage, it leads to a foul. But in this case, since Baena's handball was likely accidental and he wasn't the scorer, the play continues.Explaining VAR and handball rules

I should clarify that VAR checks if the ball touched an attacker's hand, but according to modern interpretations, it’s not always an offense unless it's deliberate or the scorer’s handball. I don't need to run any complex processes here; it’s general knowledge I can summarize.

I’ll include concise points: a brief explanation, key points from IFAB Law 12, and two specific cases applied to the incident. I’ll address common questions, like what "immediately after" means, the implications of a deliberate handball, and any considerations regarding unnatural body positioning.

Actually, if an arm makes the body unnaturally bigger, it’s considered an offense regardless of intention, which plays into determining whether a handball was deliberate. I need to emphasize that not every contact with the hand or arm is an offense; it depends on how the body is positioned.Explaining handball offenses

I need to clarify that not all handball offenses are considered "deliberate." If Baena's arm was in an unnatural position that blocked or controlled the ball, that would indeed be a handball offense, nullifying the goal. There are handball offenses defined by Law 12, such as making the body unnaturally bigger or having a deliberate handball.

The 2021 change means that accidental handballs by attackers leading to a goal aren't automatically offenses unless the scorer immediately handles the ball. So, in this case, if Baena’s contact was incidental and not deliberate, the goal stands.

I’ll summarize the rule: A goal is disallowed only if the scorer directly scores with a hand or arm or immediately after touching it. An accidental handball by a teammate earlier in the phase isn’t an offense. If Baena's handball was deliberate or if he gained control and created a scoring chance, then it would be an offense. However, VAR likely concluded it was incidental.

"Immediately" means in the next action or touch; the scorer's handball must be right before scoring, but direct link is crucial. I’ll explain this succinctly in Chinese, avoiding any unrelated match details.
