#3. Joe Rogan believes Elon Musk is good for Twitter

Joe Rogan on Elon Musl and Twitter

Elon Musk recently completed his multi-billion dollar acquisition of Twitter after months of back and forth negotiations. Following the takeover, Musk has already fired CEO Parag Agrawal and policy chief Vijaya Gadde, among others.

However, Joe Rogan feels Elon Musk's ownership will be good for the microblogging platform and hailed the business tycoon for using his wealth to make space for free speech:

"That's the best...What Elon wants to bring back to Twitter is reasonable exchange of ideas...But it's just rare that someone is that wealthy that they can do that and he was very left-leaning for most of his life until really recently. The pandemic in particular and the way people have sort of enforced these ideologies regardless of whether or not the science supports it. He thinks it's bad and I think it's true."

Watch the video of Rogan's comments below:

Elon Musk made his intentions with Twitter clear in a statement he released after acquiring ownership, which reflects the same hopes that the UFC commentator has.

#2. Dr. David Abbasi suspects Calvin Kattar tore ACL at UFC Vegas 63

UFC Fight Night: Kattar v Allen

The UFC Vegas 63 main event came to an anticlimatic end when Calvin Kattar's knee buckled in round two due to a knee injury that he sustained in the first round. All it took for Arnold Allen was one leg kick to make Kattar go down and pick up a TKO victory.

Following the fight, orthopedic sports surgeon and MMA doctor Dr. David Abbasi took to social media to analyze the nature of Kattar's injury. Abbasi is well-known for breaking down fighter injuries following UFC events.

Looking at Kattar's KO, Dr. Abbasi deduced that there was a possibility that Kattar had suffered a complete ACL tear:

"Look how he comes down landing in this dynamic valgus position here. His dynamic valgus positioning on the landing is very concerning for an ACL complete tear and see how he avoids putting weight on it afterwards. Anytime I see somebody landing in the position and refusing to bear weight on it, it's an ACL tear unless proved otherwise to me. "

Dr. Abbasi further added that if it was indeed an ACL tear, Kattar would require surgery. The fighter has not provided any further update on the injury at the time of writing this article.
