Meaning of 首ひねり in the following sentence


A boxer has just managed to bring down his opponent landing his final punch.
However, he surprisingly goes down too. [Here you can see the whole
page](https://i.stack.imgur.com/2B6Eg.jpg). His trainer comments with this
sentence:

> [スリッピングアウェー]{首 ひ ね り}と同時に[とんで]{・・・}たか……ガキ〰〰〰

Why has 首ひねり been used as furigana for スリッピングアウェー? I researched 首ひねり and it is
a sumo move in which a wrestler grab the opponent's head with one hand and
with the other tries to throw him down, but, from the image, to me it looks as
if the boxer bumped into or was hit by his opponent's arm after landing the
final punch, though there are some spinning marks drawn. Not understanding
this, I am also not able to understand the second part of the sentence. Could
you help me understand why 首ひねり was used here and what is the general meaning
of the sentence? Thank you for your help!




首ひねり is obviously used to explain スリッピングアウェー, so it shouldn't be another
difficult technical term. You can forget the sumo move.

首をひねる (literally "twist a neck") is a common set phrase (not specific to
boxing) that means rotating or coking your head. Most of the time this phrase
also figuratively means "to think deeply" or "to be puzzled" (similarly to "to
shrug"), but its figurative meaning is not relevant now. In this context it
just refers to the physical movement of rotating your head in order to absorb
the shock of the punch, as illustrated in your picture and [this

obvious to you, but remember the [masu-stem can be used to nominalize a
verb](https://japanese.stackexchange.com/a/32311/5010).

Next, I believe this [とぶ]{・・} is 意識が飛ぶ, which is another set phrase meaning
"to faint". Note the dots beside とぶ, which often imply some slangy/derivative
meaning of a word is used. For example [やる]{・・} might mean 殺る or "to kill".

Therefore the basic meaning of the sentence is "Boy, you had been unconscious
since your last 首ひねり move".
