Brian Urlacher gets pain-killing injections and often will not admit to feeling like he has a concussion in order to stay on the field. Urlacher appeared on HBO's "Real Sports" and said that he has been shot up with Toradol, an anti-inflammatory that can decrease pain by reducing inflammation. "It's normal," Urlacher said. "You drop your pants, you get the alcohol, they give you a shot, put the Band-Aid on and you go out and play." Andrea Kremer pointed out in the segment that regularly using the drug can lead to kidney failure and gastrointestinal bleeding. Urlacher professed to not knowing the side effects but says it didn't really matter. "First of all, we love football," Urlacher said. "We want to be on the field as much as we can be. If we can be out there, it may be stupid, it may be dumb, call me dumb and stupid then, because I want to be on the football field."
