( CNN ) -- Former New England Patriot player Aaron Hernandez was transported from his Massachusetts jail cell to a nearby hospital this weekend , according to Bristol County Sheriff Thomas Hodgson . Hernandez spent less than a half hour Saturday afternoon at St. Luke 's Hospital in New Bedford , Hodgson told CNN . Hodgson was unable to disclose why Hernandez was admitted to the hospital because of federal health privacy law , except to say that it was not caused by a fight , security issue or any other problem at the jail . Hernandez has since returned to Bristol County House of Correction , where he awaits a trial on first-degree murder charges in the June 2013 death of semi-pro football player Odin Lloyd . Prosecutors allege Hernandez orchestrated the killing of Lloyd , whose body was found in a remote spot at an industrial park about a mile from the former Patriots player 's home . He 's also charged with two counts of first-degree murder in the July 2012 deaths of Daniel de Abreu and Safiro Furtado . The two were shot to death in what prosecutors described as an ambush as they drove on a Boston street following a `` chance encounter '' with Hernandez at a lounge . Hernandez may have been the shooter in that incident , according to court documents . He has pleaded not guilty in all three killings . Hernandez played tight end for the New England Patriots for three seasons after leaving Florida for the 2010 NFL draft . The Patriots dropped Hernandez the day he was arrested in Lloyd 's death . A year after Odin Lloyd 's death , loved ones cling to memories . Source : Hernandez 's anger over two trivial incidents linked to killing . CNN 's Leigh Remizowski contributed to this report .
