Largest comeback in a Rugby Union World Cup match

The greatest comeback to win in a Rugby World Cup match is 15 points and was achieved by Romania who trailed 0–15 at half-time, only to emerge victorious 17–15 in their pool match vs. Canada at Leicester City Stadium, in Leicester, England, UK, on 6 October 2015.

Captain Mihai Macovei was the hero with two tries in the final 30 minutes of the game to put them within touching distance.

Florin Vlaicu scored a late penalty to hand the Romanians the win and their slice of Rugby World Cup history.

When trailing 0–8 at halftime, their coach, Lynn Howell, had told his team to "pull your socks up", which seemingly did the trick.
