Saracens' Champions Cup tie against Clermont-Auvergne had to be moved as sporting fixtures in Europe and the US were hit by bad weather.
The Met Office issued an amber alert - its second highest warning - for snow across parts of Wales, the Midlands and northern and eastern England on Sunday.
The blanket of snow was enough to force Saracens' clash at the Allianz Arena to be postponed until Monday due to "adverse weather".
The fixture will now kick-off at 5:30pm on Monday, and take place behind closed doors.
Snow affected fixtures across Europe, too, with Dutch football fixtures impacted heavily.
Feyenoord's match at FC Utrecht was postponed despite the best efforts of the ground staff, who had to clear the pitch at the De Kuip, which was deemed unplayable.
Ajax's crunch game against PSV Eindhoven was delayed by 15 minutes as the snow was cleared.
The game did eventually go ahead with Ajax winning 3-0.
Across the Atlantic, many of the NFL's Sunday fixtures were played through a veil of snow.
The clash between Indianapolis Colts and Buffalo Bills somehow went all the way into overtime in difficult conditions. The Bills ultimately overcame the Colts 13-7.
There was no snow in South Africa but thunderstorms caused havoc, so much so that the final round of the Joburg Open was abandoned, meaning the players went into a fifth day on Monday.
Watch the above video to see how the extreme weather affected sports across the world at the weekend.
