Morale and condition, fitness, stamina, hard tackling, hard defend or attack, age, and grade of the pitch are some. - I played many games with 0% condition and 0% morales, and I had 1 or max 2 injuries in single match, I seen 4 injuries in single match for my friend, now I see 5 injuries in single match, this is BUG or trollololololo
There are many things that contribute to injuries. - good, but who seen 5 injuries in single real match?
Fifteen red packs heals any injury. - hmmm if all 5 injuries are for 5+ days, so 5*15 red packs, who have 75 red packs after 2 sesons? only token buyers...
