One month following the tragic passing of Bengals wide receiver Chris Henry, the NFL lost another active player when Bears defensive end Gaines Adams died at the age of 26 after going into cardiac arrest on Sunday. Adams' death marked the eighth time since January 2007 and the 11th time since 2000 that an active NFL player has died.
Here's a look at the players and the circumstances of their deaths:
Adams , 26,went into cardiac arrest at his family's home in Greenwood, S.C., early Sunday morning and was pronounced dead about an hour later at Self Regional Hospital. An autopsy conducted Sunday showed Adams had an enlarged heart, a condition Kelley-Clark said can often lead to a heart attack.
Henry , 26, died Thursday morning from severe head injuries suffered after falling out of the rear end of a truck Wednesday afternoon in Charlotte. The accident occurred following a "domestic situation" in which Henry subsequently jumped into the back of the truck being driven by his fiancée.
Cooper and Smith were among four men reported missing after they embarked on a fishing trip off Florida's Gulf Coast in early March. On March 2, Nick Schuyler was rescued after being found clinging to an overturned boat. The Coast Guard suspended its search the following day. The bodies of Cooper, Smith and William Bleakley were never discovered and they are presumed dead.
Taylor died after being shot in the leg by an intruder in his home in South Florida the day before. On Nov. 30, 2007, four people were detained in connection with Taylor's death and eventually arrested. A fifth suspect was arrested in May 2008. Though one of the suspects accepted a plea deal and was sentenced to 29 years, a trial has yet to take place.
Hill died while jet-skiing with a friend on Louisiana's Lake Pontchartrain. Rough waters knocked the pair off their jet ski. Hill helped his friend, Ashley Blazio, stay afloat – and alive – by giving her survival instructions until he was pulled under by the currents.
Nash collapsed and died after an appearance in a charity basketball game in St. Louis. The charity event was a fundraiser to benefit the Darris Nash Find A Heart Foundation, a charity which raises funds for heart transplant research. It is believed that Nash was stricken with a heart condition.
