Here's video of Dak Prescott lying to our face (though we understand why) ... telling TMZ Sports he doesn't know much about the criminal case involving his teammate, Ezekiel Elliott.
Suuuuure ...
The Dallas Cowboys QB insists we know more than he does when it comes to the security guard who's pressing charges against Elliott ... though that's hard to believe considering Dak and Zeke are BFFs.
Prescott was out at Avra in Beverly Hills on Sunday night (one of the hottest restaurants in town) where we asked how Elliott was holding up after 19-year-old Kyle Johnson filed a criminal complaint against the RB for knocking him to the ground at the Electric Daisy Carnival.
