Dirk Nowitzki is sticking with the Dallas Mavericks at least through the 2010-11 season.

A week before opening training camp, the Mavs made sure their superstar forward remains under contract for the next five seasons with a lucrative extension Tuesday.

Nowitzki, 28, already was signed for the upcoming season and had a $16 million-plus option for 2007-08 under the maximum contract he signed in 2001. The new deal guarantees that season, plus tacks on three more. He'll turn 33 the summer his new contract expires.

Terms of the deal were not released, but with basic raises the extension is likely worth around $60 million.

The tax evasion case of Dirk Nowitzki 's coach and mentor will go to court on Oct. 9, according to the NBA All-Star's hometown newspaper.

The Wuerzburg Main Post reported Thursday that Nowitzki is not expected to appear at the trial of Holger Geschwinder, who works with the Dallas Mavericks player in the offseason.

On Wednesday, Mavericks' owner Mark Cuban said that the club will continue to discuss an extension on the contract of Josh Howard.

Donnie Nelson hopes to have the deal finalized prior to the start of training camp.

"Everybody prefers to find the common ground and get some security for both sides," Nelson said. "We're going in a decent direction and there's a pretty good possibility something can get done. But there's no real sense of urgency. If for some reason nothing happens, then he plays for us this season and we revisit it next summer."

Devin Harris estimates he has averaged 600 to 700 jump shots every day for the past month, shooting from places where the Mavs' offense will allow him to.

"I had pretty much a great run at San Antonio, but the last two series I could have played better," Harris says. "The way Miami was playing me, it was almost like they were playing five-on-four. They weren't respecting my outside touch.

"In the regular season, you may get away with it. But the further we went in the playoffs ... It frustrated me."

Shawn Kemp's planned workout at the Berto Center never materialized Monday, and it's unlikely the six-time NBA All-Star will receive another invitation from the Bulls, K.C. Johnson of the Chicago Tribune reports.

Kemp experienced travel problems late Sunday night but still arrived in Chicago early Monday morning. Instead of working out with the Bulls, he traveled to his hometown of Elkhart, Ind., to visit an ailing relative.

Kemp, who retired in 2003 after 14 seasons because of weight issues, also missed a planned workout with Dallas earlier this year.

Danilo (J.R.) Pinnock, the 58th pick in the NBA draft earlier this summer, has signed a contract with the Lakers.

Pinnock, a 6-foot-5 guard who entered the draft following his junior year at George Washington, was taken by the Mavericks before being traded to the Lakers for a 2007 second-round draft choice.

Pinnock averaged 14.5 points, 5.3 rebounds, 3.1 assists and 2.5 steals for George Washington last season. He then played for the Lakers in the Summer Pro League and averaged 10.6 points and 2.3 assists in 24.5 minutes.

Terms were not announced Wednesday by the Lakers.

With Sam Vincent promoted to the Dallas Mavericks' bench, the Fort Worth Flyers will hire Sidney Moncrief.

According to sources, the team has scheduled a news conference on Tuesday at the Fort Worth Club.

New coach Don Nelson will bring Dallas Mavericks assistant coach Larry Reilly with him to the Warriors bench, according to sources with both teams.

Reilly has spent the past four years as an assistant coach with the Dallas. His contract has expired, but the Mavericks source said he was welcomed to re-sign with Dallas if he so chooses. He will fill the vacancy left by John MacLeod, who left the Warriors after one season.

The Dallas Mavericks added Sam Vincent as an assistant coach Thursday to replace Rolando Blackmon, who was promoted from the bench to the team's director of player development in July.

Vincent was the coach of the Fort Worth Flyers, who were the runner-ups in the NBA Development League. He was also an assistant coach for Dallas in summer leagues games, and the head coach of the Nigerian National team during the 2006 world championships.
