Latest UFC rankings update: Andrei Arlovski cracks Heavyweight Top 10 after Bigfoot Silva knockout

For the second straight week, the Ultimate Fighting Championship (UFC) Heavyweight division rankings have experienced a major shake up.

Even though he wasn't in mixed martial arts (MMA) action last weekend, struggling standout Alistair Overeem continued to slide thanks to Andrei Arlovski, who scored a first round knockout of Antonio Silva on Saturday night (Sept. 13, 2013) at UFC Fight Night 51 from Nilson Nelson Gymnasium in Brasilia, Brazil (read details here), to vault himself seven slots higher.

"Bigfoot," meanwhile dropped five positions and nearly landed outside the Top 10.

No other super notable movements with the exception of Holly Holm, who made her debut in the women's Bantamweight division even though she has yet to compete inside the Octagon.

Here's what the rest of the field looks like courtesy of UFC.com. Note: (+/- = movement in rankings, *NR = Not previously ranked).
