Utah Jazz owner and CEO Greg Miller called 14-time All-Star Karl Malone "too unreliable and too unstable" to help his former team as an assistant coach Friday night.

He also claimed that Malone lied to a newspaper about having to use a scalper to purchase tickets to a Jazz game in a blog post.

Miller also posted a scathing Twitter post earlier on Friday.

"Hey Karl-you're lying, you have my number. Next time you need a seat to a Jazz game, call me. You can have mine," said Miller.

Malone and Miller have a long history of feuding over past issues regarding the Jazz organization, including former head coach Jerry Sloan and former guard Deron Williams.
