Vincent Jackson -- a 3-time Pro Bowl wide receiver -- was found dead in a hotel room in Florida on Monday, officials confirm. He was only 38.
The former San Diego Chargers and Tampa Bay Bucs star was discovered by a housekeeper inside his room at the Homewood Suites hotel in Brandon, Florida (located in the Tampa area). Cops have released pics from the scene.
The WR finally retired from the game in 2016. Jackson earned 540 receptions, 57 TDs and more than 9,000 receiving yards during his 12 seasons in the league ... and reportedly made more than $71 million in contract money during his NFL run.

The Chargers released a statement Monday ... saying, "We are shocked and deeply saddened by news of Vincent Jackson's sudden passing."
"Vincent was a fan favorite not only for his Pro Bowl play on the field but for the impact he made on the community off of it. The work he had done on behalf of military families through his foundation in the years since his retirement has been an inspiration to all of us."
"We simply cannot believe he's gone, and our hearts go out to his wife, Lindsey, their children, his parents, former teammates and everyone whose lives were touched by having known Vincent."
