Ezekiel Elliott was sitting courtside at the Dallas Mavericks-Boston Celtics game in Texas on Wednesday ... showing ZERO concerns about his team's massive NFC East showdown with the Eagles this Sunday.
The superstar running back was seen smiling, chattin' it up with players and even doing his signature "Feed Me" dance on the jumbotron.
Yeah, didn't seem to be nervous for Philly at all!!!
Of course, perhaps on the inside he's feelin' differently ... 'cause this IS a huge game for the Cowboys this weekend.
If Zeke's squad loses, their season is essentially over.
