Philadelphia Eagles general manager Howie Roseman announced in a news conference that coach Andy Reid's absence from the start of Sunday's walkthrough practice was because his son, Garrett, had been found dead in his room at Lehigh University.
"He's been strong for us, we're going to be strong for him right now," Roseman said before turning the news conference over to Lehigh University's chief of police, who said there was no evidence of foul play in Garrett Reid's death.
An investigation by the coroner's office is underway. No cause of death had been determined.
"What I can tell you is this morning we were contacted by the Lehigh campus police department and (were) requested to respond for the discovery of a deceased male," Northampton County coroner Zachary Lysek told The Associated Press. "We are conducting an investigation with the cooperation of the Lehigh campus police department, and I personally pronounced Mr. Reid deceased at the scene."
The last time Andy Reid was believed to have missed a practice was when he was attending a 2007 court date for Garrett, who had been arrested on drug and weapons charges, according to Jeff McLane of the Philadelphia Inquirer.
Garrett, 29, and his younger brother, Britt, each had drug problems in the past.
He and Britt were arrested on drug charges after two separate traffic accidents in 2007. Garrett Reid was imprisoned off and on through 2009.
Garrett Reid had rebounded from his troubled past and was assisting the Eagles' strength coaches at training camp. Many of the coaches stay in the Lehigh dorms.
We extend our deepest condolences to the Reid family and all members of the Philadelphia Eagles organization.
