New Japan's English website posted that Ospreay is dealing with a neck injury, and had subsequently been pulled from a non-tournament tag team bout on Monday as a result.
The specific nature of the injury is unclear, though the site states that Ospreay, "is not suffering from any skeletal or nervous issues."
His status for a G1 tournament match on Thursday against Kota Ibushi is up in the air, pending a medical evaluation.
Tweeted Ospreay about the news, "Sorry I couldn’t make it out there guys. I’m in a huge amount of pain right now but New Japan is giving me all the best treatment and taking great care of my health. I’ll do my best to continue the G1."
Ospreay thus far has earned two points in Block A of the G1, defeating Sanada, but losing to Lance Archer.
