Every Sunday, The MMA Corner will take a look back at the biggest news of the week.

On this week’s installment, we discuss the continued drama around former three-time UFC title challenger Chael Sonnen. After failing an initial pre-fight drug test for Anastrozole and Clomiphene, it has been revealed that the 37-year-old also failed a second test for both human growth hormone (HGH) and recombinant human erythropoietin (EPO). Being that Sonnen has already opted to hang up his gloves, will fans remember him for his fights inside the cage? Or will his multiple failed drug tests be his legacy?

We also look at the recent announcement that Tyron Woodley will replace Hector Lombard against Dong Hyun Kim at UFC Fight Night 48 in Macau on Aug. 23. Is this Woodley’s chance to get back into contention after his lackluster performance against Rory MacDonald at UFC 174? Does this new match-up have the same appeal as the Lombard-Kim pairing?

Finally, we look at an intriguing piece of news from the UFC. The promotion has partnered with Vale Tudo Japan/Shooto for a reality show that will reward the winner with a UFC contract. However, unlike the promotion’s flagship reality show, The Ultimate Fighter, the show will feature a round-robin format and take place over an eight-month time frame. Does this spell the end for international editions of TUF? Will this new format help breathe new life into future seasons of TUF?
