The feud between Nuggets forward Kenyon Martin and Mavericks owner Mark Cuban is far from over.

Cuban kicked things off by insulting Martin's mother after Denver's Game 3 win over Dallas in the second round.

"He's a coward," Martin told HoopsHype.com of Cuban. "He couldn't face it. You all read the only apology that he's made [on his blog].

"The world got to see it before the person who it was meant for got to see it. That tells you how that goes. I ain't never known nobody apology to somebody through other people."

Cuban said after issuing the apology on his blog that doing so was a mistake.

"I still intend to apologize to Ms. Moore," Cuban wrote of Lydia Moore, Martin's mother. "I made a mistake and will keep my commitment."
