Drew Brees Reveals He Can No Longer Throw With Right Arm

One of the greatest right arms in the history of sports no longer works.

Drew Brees made the shocking revelation this week ... admitting he can't throw overhand anymore.

"Look," the future Hall of Famer said on Tuesday on ESPN Radio. "I'll let you in on a little fact. I don't throw with my right arm anymore. My right arm does not work. So, when I throw in the backyard right now, I throw left-handed."

Brees said on the show it all stems from the devastating shoulder injury he suffered while playing for the San Diego Chargers during the 2005 season.

You'll recall, following a fumble, Brees fell awkwardly on his throwing arm ... dislocating his shoulder and tearing up several important pieces of his body in the process.

Docs were able to fix him ... and he went on to have one of the best NFL careers ever with the New Orleans Saints -- but he said he's reeling from it all now.

The former quarterback said he's suffering from a "degenerative shoulder" ... as well as "all kinds of arthritic changes."

Brees then revealed if he could somehow get it to work -- he "would absolutely still be playing."

The 44-year-old added that, thankfully, he is able to be somewhat athletic with his right arm still ... saying at least pickleball isn't out of the equation at this point.

"I can play pickleball because it's below the waist," he said.
