Today a very serious and possibly tragic event was witnessed by a stadium full of football fans and countless viewers on television. Tulane University was playing Tulsa University in Tulsa, Oklahoma. With two seconds left in the first half a seemingly minor head-to-head collision of two Tulane players left Devon Walker unconscious and non-responsive on the field (http://espn.go.com/college-football/story/_/id/8352006/tulane-safety-devon-walker-hospitalized-suffered-broken-neck-collapsed-lung-hit ). Medical people rushed to the site to begin administering aid, including CPR and a tracheotomy, to the stricken player. An ambulance came onto the field, and after several tense minutes of work on Walker, he was loaded into the ambulance and taken to nearby St. Francis Hospital. The latest report I have is that Walker suffered a broken neck and a collapsed lung.
