REUTERS: Atalanta's match away to Udinese on Sunday was called off because of a waterlogged pitch, the club said on Twitter.
The referee took the decision about an hour after the scheduled kick-off following several pitch inspections. Serie A confirmed the decision on its website.
Atalanta, who visit Ajax in the Champions League on Wednesday needing a draw to reach the last 16, are ninth in Serie A with 14 points while Udinese are four points behind in 14th place.
