UFC 246 and Cowboy's Limp

So the notorious returns to the octagon against Cerrone on Saturday. Plenty are saying Conor is sure to be victorious but I don't think the result is that certain. What happens if Conor is looking to assess Cowboy's rhythm and timing and gets caught with a head kick while adjusting to a 1-2 from Cowboy? Cowboy has great wrestling and jiu jitsu but, in fairness, Conor has been drilling wrestling since the camp for the Khabib fight, always drilling jiu jitsu and proved what a good clinch game he has in the Diaz rematch. I think Cowboy can upset the odds but hope Conor wins. Anyone who watched Embedded yesterday saw Cowboy's limp. He reckons he kicked the bag wrong or something and that it's nothing serious. But my expectation of the chances of a victory for Conor went up after seeing it. I tweeted asking what would happen if, hypothetically, Cowboy pulled out and another fighter got bumped up to save the main event but I didn't get a reply. I was thinking Anthony Pettis is there but he's scheduled at 155. But maybe he'd just not cut any weight in the last couple of days.
I wonder why Holly Holm is the co-main? She doesn't have the greatest record lately. But she seems to always be a draw since beating Rhonda Rousey. Pettis is facing Carlos Diego Ferreira. I don't know much about Ferreira to be honest but The Weasle is predicting a Ferreira victory, so he must be good. Further down the card the sexy Maycee Barber is facing the veteran Roxanne Modafferi. That should be an interesting fight. It's probably Barber's toughest test to date on her quest to become the youngest ever UFC champion.
On a slightly different note, my phone is breaking down and I can't afford a new one. I don't want to but I'm considering selling my Bellator Dublin ticket to finance a new phone. I'll put it off as long as I can. Hopefully it won't come to that. I don't want to miss the event.
