Care to share the source for that? Because from what I’m seeing here -- https://www.proboxingodds.com/fighters/Subriel-Matias-4492

The odds aren’t really that close.
Matias -150
Smith +130

I guess I’d still bet on Matias here despite the news you mentioned. I’m not really aware of the ED issue you’re talking about, but since Matias is more popular than Smith, that makes me think he still takes this fight.
