Arnold Allen wins by TKO after Calvin Kattar injures leg

Arnold Allen won his 10th consecutive UFC match Saturday night when Calvin Kattar injured his leg in their featherweight main event of UFC Fight Night in Las Vegas.

The fight was called eight seconds into the second round when Kattar dropped in a heap. Kattar actually injured the leg near the end of the first round when he landed awkwardly off a flying knee attempt.

He came out for the second but didn't last long.

"That's never a TKO by injury," Allen said afterward. "I can't really ask for a title shot off this."

Allen improved to 19-1 while Kattar dropped to 23-7.
