For those that do not know Seven time Moto 2 and MotoGP champion Marc Marquez underwent surgery to again work on the humorus that he broke at the first MotoGP race of the season.  He missed the entire season.

The surgery lasted eight hours.

At this point I don't see him being fit to ride for the Preseason testing in Sepang and if the season starts without any Covid  dellays he may miss some races.  It appears to be a very serious injury.  The article suggests that he could miss all of 2021.

Well that kinda sucks
