first , he will recuperate for the next league game (Saturday) if i have doctor 8?
Now the doctor level was equal, if you got those doctor when he was injured it's maybe prevents some weeks of injury(the bb postet a formula for that, but i ain't recognized that^^).
The healing is a bit random, but it is possibel that he was fit on saturday.
and two , he already have 53 minutes in this week.. he will get the train this week ?
yes he get training for this minutes, when he ain't got those minutes it is also possibel to train ft etc. and also the injured playeers who don't play gets training.
