MotoAmerica Superbike racer Johnny Rock Page has been ruled unfit to race at this point of the 2017 season because he is suffering the effects of multiple concussions, including his most recent concussion suffered in a crash during 2016.

A press release issued by Page last week included a statement sent to him from MotoAmerica Chief Medical Officer Dr. Raymond Rossi, which Page shared with Dr. Rossi’s consent. Roadracing World also verified with Dr. Rossi that the statements were in fact from him and accurate.

“As per our ongoing discussion,” wrote Dr. Rossi, “you are currently unfit to participate with MotoAmerica due to your continued complications from multiple previous, as well as your most recent concussive event at Road Atlanta in 2016.

“Evaluations by a neurologist and neuropsychologist, as well as ImPACT neurocognitive testing, have shown significant continued impairment. Until your neurocognitive testing normalizes, you are at great risk if you sustain another concussion. It is therefore not possible for you to compete with MotoAmerica at this time.”

“I have to be patient with this latest injury so that it is completely healed,” Page wrote in the release. “The concussions have stacked up over my profession road racing career. [I] hope to be back on a Superbike with MotoAmerica as soon as I am recovered.”

Page has competed in the MotoAmerica Superbike Championship, and the AMA Pro Superbike Championship before that, for several seasons.
