Alexander Gustafsson, Phil Davis Question Legitimacy Of Anderson Silva Training Video

After a unique video surfaced online on Tuesday that showed Anderson Silva knock out one of his training partners, several of Silva's peers in the UFC have commented on the clip, questioning its' legitimacy.

The video, which features Silva knocking out training partner Douglas Moura with a flying knee and then continuing to pummel him while he's on the ground, has UFC Light Heavyweight contenders Alexander Gustafsson and Phil Davis calling "B.S."

"He didn't look knocked out to me," said Davis.
