Weekend warriors: Daniel Straus takes tournament and Michael Chiesa scores upset

Maggie Hendricks

The MMA world continued to turn as you were off celebrating Mother's Day, so here's a quick rundown of what you need to know from the weekend.

As you can see from the video highlights, at Bellator Daniel Straus took the featherweight tournament final in a unanimous decision over Marlon Sandro. With that win, Straus will get to vie for the Bellator featherweight belt, which is currently held by Pat Curran. Patricky Freire will fight for it next.

Bellator was also marred by controversy as Waachiim Spiritwolf was winning his bout with Marius Zaromskis. However, Spiritwolf sustained a cut too severe to go on. For if the stoppage was justified, let's turn to veteran MMA journalist Jim Genia:

Tough break for Waachim Spiritwolf on that cut-stoppage, as he was wrecking Marius Zaromskis.  However, in no way, shape or form do I question that stoppage.  Dr. Sherry Wulkan was the one who waved the bout off, and she's been a ringside physician for more MMA bouts than 99.9% of the world has even read about on the Internet.

Marcin Held won with a quick heel hook, and Marcus Galvao took a decision to earn a spot in the bantamweight tournament finals.

Quarterfinals were underway at set of "The Ultimate Fighter." Before the bouts, Dana White broke the news about Dominick Cruz's torn ACL to both teams before confirming that Cruz will stay on to coach for the rest of the season.

In the first quarterfinal, James Vick pressured Joe Proctor and avoided his submissions to take the two-round decision. Michael Chiesa moved on to the semifinals by scoring a TKO over Justin Lawrence in the third round. Lawrence was considered the favorite coming into the show, so Chiesa's win was an upset.

This Friday, Team Cruz's Vinc Pichel will fight Team Faber's Chris Saunders and a bout between teammates, as Team Faber's Al Iaquinta faces Andy Ogle.
