Maybe suspended for violating journalistic standards, unless he was on the edge and they are looking for a reason to clip him. Of course, they don’t even need a reason.
Nothing is going to happen to Borges. This is the new world that newspapers find themselves in where they have to be first to break a story, they don't necessarily have to be correct.
Let's pretend that this story is true, it's a bombshell and not only that, but Borges got it first ... even before Twitter. That rarely ever happens any more. And not only that but this is such a big story that it drives the offseason. Unfortunately, newspaper editors have one job now: get noticed. I doubt that the editor even asked Borges if his source was credible (not because Borges is a great reporter, but because he's a veteran guy and this doesn't happen to them). My guess is that the editor saw this, his eyes widened and was like, "Holy fuck, we're relevant again! (At least for one day)" and didn't think twice.
It completely blew up in their faces but TBH, it could have happened to anyone at any paper. It's the new nature of the beast. But Borges might get a public slap on the wrist, but if the Herald editors are being honest with themselves, they'd do the exact same thing tomorrow.
There's no doubt in my mind.
