UFC 168 was one of the biggest nights of fights in UFC history topped off by Rousey defeating Miesha Tate for the second time, as well as the tragic injury of Anderson Silva in his second defeat against Chris Weidman.

However two of the post fight drug tests came back as “inconclusive”.
Dennis Siver and Siyar Bahadurzada’s tests came back as inconclusive, and as a result will have their B samples tested.

Siver bounced back from his loss to Cub Swanson with a unanimous decision win over Manny Gamburyan. While Siyar Bahadurzada extended his losing streak to 2 with his decision loss to John Howard.

The inconclusive result does not necessarily mean the fighters used a banned substance, the results could be contaminated by an outside source or item, or could have been diluted. We will keep you updated with the results of the fighters secondary urine samples.
