Yes...that is a huge "DAMN" to worry about. Good Lord, you still have the original doctor from season 17? His salary must have inflated quite a bit.
If you still haven't gotten a doctor yet, I recommend either a basic or competent doctor, depending on how much your income is. If your income is too low, just get a Basic doctor. You need more income since you are looking to expand that arena. I also recommend highly the taping injuries specialty. Taping Injuries gives a chance for an injured player to recover from the injury right after the game, I believe. Good luck with the rest of the season.
