Dallas Mavericks owner Mark Cuban did not accept DeAndre Jordan's apology.

"When is an apology not an apology?" Cuban wrote Saturday via Cyber Dust. "When you didn't write it yourself. Next"

Jordan violated an unwritten NBA rule by backing out of an oral commitment to sign with the Mavericks, instead opting to return to the Los Angeles Clippers, where he had spent his entire seven-season career.

Cuban detailed how it went down over Cyber Dust on Friday, saying he went to Jordan's home in Houston when he heard the center was having second thoughts about coming to the Mavericks. According to Cuban, Jordan said he was out on a date, then stopped responding to the owner's texts.

Turns out Jordan's "date" was actually Blake Griffin, as J.J. Redick later revealed in an interview with Grantland.

Chicago trades Sharp in cost-cutting move

In a widely anticipated trade, the Chicago Blackhawks sent alternate captain Patrick Sharp to the Dallas Stars on Friday night in GM Stan Bowman's continued effort to construct a roster within the NHL's salary-cap confines.

In return for Sharp, 33, and top defenseman prospect Stephen Johns, Chicago received defenseman Trevor Daley and forward Ryan Garbutt.

Most important, the Blackhawks shed Sharp's $5.9 million salary-cap hit and now have some wiggle room under the $71.4 million limit to continue to build the roster for 2015-16.

Daley, 31, recorded career highs with 16 goals and 22 assists in 68 games last season, and his arrival could mean veteran Johnny Oduya won't be back.

During 679 games with the Blackhawks, Sharp had 239 goals and 272 assists.
