A dead fish was thrown on to the pitch at the Luzhniki Stadium during England's World Cup semi-final clash against Croatia.
The bizarre incident occurred in the first half, as England took a 1-0 lead.
It is not clear from what set of supporters the aquatic creature was thrown from, but it was snapped by photographers shortly after landing.
A gentleman quickly hurried onto the pitch to collect the fish to prevent it getting in the way of play.
It is also not yet known at what point during the first half the fish was thrown on to the pitch.
England took an early lead when Kieran Trippier stroked home a brilliant free-kick after five minutes.
Dele Alli was brought down by Luka Modric on the edge of the box and his Spurs team-mate stepped up to do the rest.
