Why are people not more concerned about Beterbievs knee? I'm worried sick over her

I must be in the wrong I guess, and hopefully someone can explain, why aren't more people and analysts talking about Beterbiev making quite a quick turn around with a ruptured meniscus?

I just saw the open workout and bb didnt hit pads or do anything quick / sharp with his footwork. I'm kinda worried we're going to get shades of the Sergio Martinez knees vs Cotto
