They were actually both cleared medically and will be OK to compete again soon :). It depends, the champions sometimes have a rematch clause in their contract, but in this case, its just because: a) It wasn't a definitive win for the champion; and b) there just isn't any other deserving contender at this time. Carla Esparza is a former champ and riding a two fight win streak. If she can finish Michelle Waterson in their fight, then that could be the next one. But a fight also has to sell and Esparza just isn't an exciting fighter. But I agree with you too, a challenger should kind of earn another shot at the strap. People will be watching the Jessica vs. Rose fight closely.
