When a guy goes on injured reserve, he does not count against the cap. So if a guy is making $700 a week and he's out for two weeks, and then you bring in a guy to replace him for $400 a week, you're actually saving $300 a week on the cap. You still pay (the first guy) his full salary; it just doesn't affect the cap.
