It will also be Parker's first fight under the tutelage of new trainer Andy Lee, after splitting with his long-time coach Kevin Barry following the Fa fight in February.
The 29-year-old says he's excited for the fight in what is a new chapter in his career.
"I'm looking forward to it," he said. "Andy [Lee, his new trainer] is a very good teacher. My style hasn't changed a lot but it's improved and looks a lot better. It's refreshing.
"It's a new voice. The whole package, the whole team, different gyms -- it's all exciting and all new. I feel like I'm at the beginning my career again."
Chisora is looking to bounce back from a unanimous decision loss to undisputed cruiserweight champion Oleksandr Usyk late last year in hopes of a second shot at a world title.
"I'm feeling good, I'm in great shape, great mind, everything has gone well and I can't complain," the 37-year-old said.
"What keeps the fire burning? Money. It keeps me on fire, keeps me going."
