There have been many cases of the short term effects of head injuries or concussions in the NFL. .
One such example is Jason Smith. Smith is a football player for the St. Louis Rams. After suffering a concussion in a game, Smith experienced a bout of dizziness and vomiting while sidelined with the head injury. While this would seem concerning, it would appear that many NFL players seem at ease with this, as Smith stated, players "get concussions all the time. You clear up and keep playing. I probably had one or two of them in camp while I was here. We hit helmet to helmet all the time, and you get a little woozy."(Coats). Another case that showcases how serious head injuries can be while demonstrating another one of the short term side effects is the case of Trent Green, former quarterback for the Kansas City Chiefs. .
On the play Green got injured, he was running and after about five yards he decided to slide to the ground to, ironically, avoid one of the jarring hits that can cause these injuries. As he was sliding, Cincinnati Bengals linebacker, Robert Geathers, hit Green during the slide. The result of this hit left Green unconscious for eleven minutes and caused him to spend the next couple of nights in the hospital as a result of his head injury (Domowitch). One last example of a player that has suffered from one of these damaging head injuries, is former Oakland Raiders Linebacker, Bill Romanowski. In an article for Sports Illustrated, Romanowski explains how he does not know how many concussions he has sustained but knows that he has had suffered both dizziness and nausea during the first three games of the 2003 regular season. Romanowski also states "I have a dull ache in my head. Each of these last few incidents, I get hit and then things get very scrambled. I get disoriented. Maybe five, 10, 15 seconds. And when I start to try to work out now, those symptoms come back"(King 102-103).
