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 chaotic week for former, three-time UFC title challenger Chael Sonnen. Just one week after his scheduled opponent at UFC 175, Vitor Belfort, revealed the details of a failed drug test with the Nevada State Athletic Commission, Sonnen took it a step further. Not only did Sonnen also fail a pre-fight drug test, the 37-year-old first tried to justify the failure, before ultimately opting to hang up his gloves for good. Did Sonnen make the right call? Or has the damage already been done?

We also look at the recent announcement that the UFC will officially launch the women’s strawweight division on July 16 in Atlantic City, N.J., as Brazilian Claudia Gadelha clashes with fellow unbeaten Tina Lahdemaki. The promotion will feature the 115-pound division on the 20th season of The Ultimate Fighter, with the winner earning the inaugural strawweight title. Could the Gadelha-Lahdemaki winner be the first to challenge the reality show’s winner?

Finally, we look at an intriguing welterweight match-up slated for UFC Fight Night 49 on Aug. 23 as former title challenger Thiago Alves clashes with Canadian Jordan Mein. After Alves’ lengthy absence from the cage, can a win over Mein propel him back into the title picture? Or will Mein improve his stock with an upset of the veteran?
