Warren Sapp says he's INNOCENT -- claiming the woman accusing him of drunkenly running her over at a 2015 Super Bowl party was so wasted that night, she's clearly misremembering the facts.
We broke the story ... Sapp is being sued by Paula Tricky -- who claims she was hanging at an ESPN party in Arizona on Jan. 30, 2015 when a sloshed Sapp came out of nowhere and bowled her over, causing serious injury.
Sapp was served with his summons earlier this week in L.A. when a process server posed as a fan and blindsided him by slapping him with his court summons.
