I'm definitely expecting artists/musicians to have some problems separately from all that, but since none of them probably need to come here for the rest of 2020 it shouldn't matter. I would think all the baseball and hockey players already have their visas even if it was an issue.
Definitely one thing I always wondered about Herrera. If he got waived and didn't catch on with another MLB team, would he lose his visa? Technically he'd still be drawing a salary (and certainly has enough money to say he's not a drain on the country's resources).
