Aye
thats why i specifically wrote "hard attacking and hard defending". Of course if you hard tackle increases the chance to make the opponent lose a player. But on the other hand the effort for doing so can wear your players out too.
Lately, the only injury I had was because of training. So i guess ill stay with what i posted above.

Logically u r right. hard attacking or hard tackling causes players to lose condition so they get injured. But if u see, at least in my case, all the players that r injured have more than 85% condition while those having 65% or less go through without injuries. So it is random I guess and nordeous tells people that low condition causes injuries to make then buy those green packs. And the cnd that decreases depends on the players stamina stats as well as opponents quality. Also, if u press whole pitch, u lose more condition.
