Former Invicta FC atomweight champion Jessica Penne wants a rematch with Michelle Waterson , but Invicta FC has other plans. “I think I’m ready for a rematch,” said Penne following her Invicta FC 6 submission win over Nicdali Rivera-Calanoc on Saturday. Penne became the first ever champion in Invicta FC history when she defeated Naho Sugiyama at Invicta FC 3 in October 2012. Waterson defeated Penne in her first title defense by arm bar to capture the Invicta FC atomweight  title at Invicta FC 5 on April 5. Invicta FC president Shannon Knapp believes Penne is deserving of another title shot, but will not make the rematch out of respect for Waterson as a champion. “I always look at it this way.  I feel like when someone becomes champion that respectfully you should give them a fight before they face that opponent again.  That’s just my thoughts on it,” said Knapp during the Invicta FC 6 post-fight press conference.
