ELP and Walker Stewart hinted that Goto was up to something else (as well as being injured), and that it had been in the news, but I can’t figure out what – any ideas?

From the commentary on today's Taichi/Oiwa match:

Walker: [Due to Goto's injury] Taichi has found himself in the hottest tournament of the summer.
ELP: Well, you know he hurt his arm but he's also… doing something else, right?
Walker: I have heard, yes – a lot of talk around the world about Hirooki Goto.

I can't figure out what they're on about. Is there some secret rumour mill with gossip that hasn't made it to English-language Google or r/njpw, or is this a joke I'm not getting, or just weak banter?
