Yasiel Puig's Thanksgiving Eve bar fight was captured on surveillance video, sources tell TMZ Sports ... and cops say they have seen the tape. Sources tell us ... the entire incident was recorded from multiple angles -- including the physical altercation between Yasiel and his sister. However, we're told investigators only saw the "outside the bar" footage -- which definitively showed Puig hitting a bar manager in the face ... and then several people attacking Puig in retaliation. As for the incident with his sister, one bar staffer who's seen the tape says the footage definitely shows Puig getting physical with the woman ... slapping her hand and pulling her hair. TMZ Sports spoke with Dodgers team president Stan Kastan last night who tells us the team and MLB officials are still investigating.
