If he takes only a Severe wound? Man, he is in the floor, bleeding and probably screaming in pain. (Be gritty when describe it, or let the player do it.) We are talking about he may have several broken bones or internal bleeding or whatever and if he does not receive medical attention soon (before the end of the second scene after being injured) could lose a limb or something worst. (He could die.) And even if he receive medical treatment, it will take to him between one to three months to fully recover. (And it’s possible than he may never recover completely.)
