Will they be included? Also, will we now be able to lift a redshirt if we want, as is the case in real life?

Nothing has changed with how redshirts work in the game.

Further research tells me the new rules only apply to football, so nothing to see here.

That's what I had thought but when you brought it up here I thought I must have missed something.

Does the game have medical redshirt?

No nothing has changed in terms of redshirting players
