Notes~
-Rachael Ostovich recently became estranged from her husband after he attacked her and put her in the hospital with a fractured orbital and assorted injuries. There's an audio recording of the incident on youtube. Not certain if that will affect her ability to compete but it could be a factor and part of the reason she opened as a betting underdog.
-Greg Hardy is a former NFL star making his UFC debut. He was featured on Dana White's Contender series twice and won both of his fights very quickly inside the 1st round via KO. He has good eyes and reflexes and his athleticism is great. It remains to be seen how far he can go with him not having as much experience as other MMA fighters. There's a chance Greg Hardy could go far due to heavyweight being a shallow division.
-Gregor Gillespie is a standout wrestler, Yancy could have a tough time if he can't stop Gillespie's takedowns. Some of Gillespie's credentials:
Gillespie attended Webster Schroeder High School where he was a standout in wrestling, winning two state titles. He continued wrestling for Edinboro University, where he was a four-time NCAA Division I All-American and won a national championship in 2007. He was the first true freshman All-American in school history, and also holds the school record for most career wins (152), most wins as a freshman (40), and highest winning percentage (.917).
