# 6.5. Medical Center: Player Health and Safety
### **Main Functions** 
The Medical Center is a dedicated facility for treating injured players and conducting mandatory medical check-ups. Both processes are essential for maintaining squad availability — **injured players or those who missed a check-up are not allowed to join matches.**
* **Injury Treatment.** Players recover from injuries over time. The recovery speed and number of players treated simultaneously depend on the building’s level and the assigned NFT.
* **Check-Ups.** Performed manually. Each check-up lasts 23 hours and must be completed before the deadline to make the player eligible for matches.
* **Capacity Growth.** Every 5 levels increases the number of players that can be undergoing treatment or check-up simultaneously.

### Important Rules
* Players who are injured or overdue for a check-up cannot participate in matches.
* Injury recovery happens automatically, even without adding a player to the Center. But NFT specialists accelerate the process using the **Medicine** skill— in this case, a player should be added to the Medical Center for a faster treatment.
* Check-up frequency depends on the rarity of the assigned NFT:
Without NFT / Common NFT: every 60 days\
Uncommon: 70 days\
Rare: 80 days\
Epic: 90 days\
Legendary: 100 days
***
### Player Health Warnings
* **Injured Players** are marked with a red medical cross in the roster.
* After recovering from an injury, player’s energy is restored via the Fitness Center, depending on its level.\
**For example:**\
\&#xNAN;*Fitness Center level 1 → restores 81% energy*\
*Fitness Center level 20 → restores 100% energy*
More information about injuries is in section 14. [Simulation of matches in Lazy Football](https://docs.lazy.football/how-to-lazy-football/match-simulation-and-roaster#in-game-player-injuries).
• **Check-up Status.** Players requiring a check-up are marked with a stethoscope:
Yellow: if fewer than 10 days remain until check-up 
Red: if fewer than 3 days remain until check-up 
Blue: undergoing check-up 
**Players who miss their check-up deadline become ineligible for matches until the check-up is completed.**

### Working with NFT Specialists
NFTs with the **Medicine** skill improve injury recovery speed. For example, a skill level of 50 increases healing speed by 100%, cutting the recovery time in half.
Medicine skill is highlighted in the Medical Center
> ❗ Check-up duration is fixed at 23 hours and does not depend on NFT.
**See the in-game table for exact multipliers, where Skill Level is your Lazy Staff NFT level, and Value is recovery time reduction (%).**

### Instant Options
* **Instant Check-Up.** The first check-up per day costs 1 Gem, each additional one increases by +1 Gem.
* **Instant Recovery.** The cost equals the sum of all remaining injury days.
**Example:** 6-day injury = 1 + 2 + 3 + 4 + 5 + 6 = 21 Gems.
You don't have to heal the entire injury at once — you can select a **partial recovery** to save Gems.
Example: with a 6-day injury, **instant** full recovery = 1+2+3+4+5+6 = 21 Gems\
You can heal **3 days** only: 1+2+3 = **6 Gems**, then wait the rest.
Plan your strategy — combining partial instant recovery with regular healing can save a lot of Gems.

### Player Management in the Medical Center
* You can remove a player from recovery at any time, preserving their current condition.
* When a player is removed during a check-up, the check-up progress is not saved.
