Drake's not letting up on NBA star Demar DeRozan ... a fan proved the beef is still going strong after seeing his jersey get tossed!!!
The Boy was performing during his first Sydney show of his "Anita Max Wynn" Australia tour Sunday when a DeRozan jersey was flung in his direction as he performed "Rich Flex."
After straightening out the wrinkles and realizing it was a DD jersey, Drake switched sports and spiked the shirt like a football straight off the stage!
