To my knowledge Boaz was not injured he was out due to Jackson wanting him to stay fresh for a second half run is what I heard. The reason behind this was he was out of competition all of last and Jackson doesnt want him to tire over the grind of the season. Cough BS cough cough.
Gambrall is definitely wrestling at 197. I don't know if he has plans to cut to 184 this year. Maybe Midlands will change his mind...or maybe he'll surprise everyone and solidify his status at 197.
