Tonight's UFC Fight Night looks to inject some ferocious Chinese talent into the light heavyweight division. Prolific finisher Mingyang Zhang has ended all 19 of his wins inside the first round, and standing in the way of a top spot in the 205 division is perennial contender Johnny Walker.

In the UFC Fight Night 257 headliner, Walker (22-9 MMA, 8-6 UFC) battered Zhang Mingyang (19-7 MMA, 3-1 UFC) in the final sequence for a TKO stoppage at 2:37 of Round 2. The first round was a slightly different story, however, with Zhang getting the better of Walker.
