Adam Vinatieri -- one of the greatest placekickers EVER -- is finally announcing his retirement ... 25 years after making his NFL debut!
The 48-year-old appeared on the "Pat McAfee Show" on Wednesday when he was asked about his football career, considering he hasn't been on a roster since the 2019 season.
"Should we just make it real?" Adam said ... "Should we just say 'Hey, we're done?' We're riding off into the sunset. You want it to be live on your show that Vinny's officially done?
