The relatively calm and quiet Eagles training camp has turned into mourning base due to the death of Garett Reid, oldest son of Philadelphia Eagles coach Andy Reid.

Garrett Reid, 29, was found dead in his dorm room by Lehigh University campus police at 7:20 a.m. Sunday.

Players and coaches gathered in a group prayer before the team's 8:15 a.m. walk-through. An hour later, general manager Howie Roseman and Lehigh University chief of police Edward Shupp addressed news reporters.

"It is with great sadness that I tell you that Garrett Reid, the oldest son of Coach Reid was found dead this morning in his room here in training camp. It's a tough morning for all of us in the Eagles family," said Roseman.

The NFL team's pre-season camp is grieving over the death of Garett who reportedly 'grew up' with the team, reports USA Today.

Shupp said that Reid was found 'unresponsive' by officers after a 911 call was placed to campus police.

"Upon arrival, it was observed that attempts were made to revive the individual, and they were unsuccessful," Shupp said. "The individual, Garrett Reid, was deceased upon the officers' arrival. There were no suspicious activities."

Northampton County Coroner Zachary Lysek, who pronounced Reid deceased at the scene, said he is conducting an investigation at the request of Lehigh campus police.

Garrett Reid was in camp working with the team's strength and conditioning staff. Apparently, he had a history of drug abuse. In 2007 he was sentenced to 23 months in prison for smashing up another motorist's car while he was high on heroin.

Joe Banner, a close friend of Reid and formerly Eagles team president, said Garrett Reid had been on an apparent path to sobriety since his sentencing to two years in a state drug rehabilitation program in July 2008 after being caught with 89 prescription pills.

Roseman said that Andy Reid requested that training camp go forward. Garrett Reid was at Lehigh attending camp with his father, the Eagles said in a statement.
