Im still trying to figure out how we made six subs as well. As I dont think any of the players would be classed as a concussion sub. Only head knock I remember was Max Johnston with hayes
Think it's called Ripcord. Run by some boys back there. Someone over here in Toronto had told me about it, as they have all the SPFL teams.
I just had to message one of the guys on Telegram for setup. (60quid a year)
