Cant wrestle in the second half of the season I think is the current rule for medical redshirt.
At this point, who knows? They give out extra years like candy.
An important thing to consider is that Yonger will be 26 in the fall. (And that's if he's birthday is to be believed, which is always questionable with Cubans). Does he still want to be wrestling in college? He would finish up older than Nelson Brands will this season which is super old.
