NFL's Chris Johnson -- I Wanna Play for the Cowboys!

Chris Johnson wants to be a Dallas Cowboy ... telling TMZ Sports he has a special message for Jerry Jones -- "Holla at me!"

The NFL running back was out at a fancy sushi dinner at Katsuya in Hollywood with his old teammate Vince Young earlier this week when we talked about his future in the league.

Chris made it crystal clear ... he's all about Big D and thinks he'd be a perfect fit.

Question is ... are the feelings mutual?!
