Hulk Hogan's busy July isn't showing any signs of stopping ... the WWE legend was just spotted out at the Detroit Lions practice -- where he ran wild on a promo with head coach Dan Campbell!!
The Hulkster pulled up to the training camp workout in a Lions-colored bandana ... and after watching Jared Goff and the boys prep for the 2024-25 season -- he got in front of a camera with Campbell, and did his thing.
