31 45 57 67 197 | Davide Astori, 31-year-old Italian soccer star, dies of heart attack, March 4, 2018

31, the 11th prime
Soccer is 11 on 11

A 31-year-old athlete, dead from a heart attack... how unlikely.

197 is the 45th prime.  He died on a date with numerology of 45.  3+4+20+18 = 45

Consider March 4 can be written 3/4 or 4/3.  Murder = 34; Killing = 43

It was also a date with numerology of 25.  Death = 25

Sacrifice = 55
Kill = 28 / 44; *Udine = 28 (Where he died)
Ritual = 27

He died on his 57th day of being 31-years-old.

57 relates to championships.  I don't follow his soccer league, but perhaps someone else does.

He also died 102-days before the start of FIFA World Cup, or a span of 103-days.

That was also 14-weeks and 4-days.  Time = 144

That's also a span of 103-days.  103, the 27th prime; Ritual = 27
