Mark Cuban -- I'm Flying In for Clippers Game ... No Plans to Talk with DeAndre

Mark Cuban tells TMZ Sports ... he will DEFINITELY be in the Staples Center Thursday night when his Mavs take on the Clippers ... more than 3 months after the infamous DeAndre Jordan flip flop incident.

You know the backstory ... Jordan made a handshake deal with the Mavs over the summer (4 years, $80 mil) only to back out and re-sign with the Clippers.

Cuban was clearly pissed about the situation -- but says he got over it -- and DeAndre eventually issued a public apology to Mark.

Still, you KNOW how bad Cuban wants to win this game tonight.

We also asked Cuban if he had any plans to speak with DeAndre -- his response? Nope.
