With less than two months until the NBA preseason tips off, the Boston Celtics have become radio nomads.

Entercom Communications announced Tuesday that Celtics games will no longer be carried on their WEEI and WRKO stations after an agreement could not be reached on a new contract. The stations had been the radio home of the Celtics since 2005.

“WEEI has had an incredible run with the Boston Celtics, from being a part of their 17th championship banner to the end of the Big 3 era,” Entercom Boston vice president/market manager Jeff Brown said in a statement.

The Milwaukee Bucks have signed Larry Sanders (6-11, 235) to a multi-year contract extension, General Manager John Hammond announced today. Sanders had a breakout year for the Bucks in 2012-13 when he posted career highs across the board with averages of 9.8 points, 9.5 rebounds and 2.8 blocks per game (2nd in the NBA). According to multiple reports, the extension is for four years, $44 million.

“By combining his God-given ability with hard work and determination, Larry has developed into one of the top young defensive players in the league,” said Hammond. “He is a very important part of what we are doing in Milwaukee, and we’re excited to announce his contract extension.”

The 24-year-old center is entering his fourth year with the Bucks and owns career averages of 6.2 points, 5.5 rebounds and 1.9 blocks per game. Last season, he notched a team-leading 26 double-doubles, one of which was his first career triple-double with 10 points, 12 rebounds and a franchise-record-tying 10 blocks at Minnesota on Nov. 30. Sanders and Kareem Abdul-Jabbar are the only players in Bucks history with a 10-block game. He finished the season with 201 blocks – just the fourth 200-block season in Bucks history and the first since Elmore Smith in 1975-76 – and had a string of 40 consecutive games with at least one blocked shot from Nov. 28 – March 4, the longest streak by a Buck in the last 25 years. Beginning with the 10 blocks at Minnesota, Sanders swatted 22 shots over a three-game stretch from Nov. 30 - Dec. 3 which stands as the most blocks in a three-game span in Bucks history, and he blocked four or more shots in five consecutive games from Jan. 2 - 9, which was the longest such streak since Abdul-Jabbar had a five-game streak in 1973.

Sanders, the 15th-overall pick in the 2010 NBA Draft, finished third in Most Improved Player voting after the 2012-13 season and earned the attention of USA Basketball with his play last year. He was invited to attend the 2013 USA Basketball Men’s National Team Mini-Camp in Las Vegas in July.

Community involvement is a priority of Sanders’ commitment to Milwaukee. He is active in supporting the Boys & Girls Club of Greater Milwaukee and earned the organization’s Community Champion Award in March after donating a scoreboard to the Pieper-Hillside location. He has also distributed Thanksgiving meals at the House of Peace, donated toys to patients at Children’s Hospital of Wisconsin, tickets to all Bucks home games for Milwaukee youth and community groups, and he hosts an annual “Larry Sanders Basketball Camp” for kids in his hometown of Port St. Lucie, Fla.

Sacramento’s arena war hit new levels of intensity this week after Seattle financier Chris Hansen was revealed as the secret source of money for a petition drive to put the city’s arena plans to a public vote.

Seizing on outrage at the news, arena supporters took to the streets Saturday, hanging more than 1,000 fliers on front doors asking residents who signed the petitions to withdraw their signatures. “Don’t let Seattle money steal away our chance at 4,000 jobs for Sacramento!” the fliers urged.

Arena backers, a group that includes many of the city’s prominent business people and politicians, argue the Seattle funding offers proof that the two-month-old petition drive is really an attempt to derail the city’s downtown arena plans and push the Kings out of town.

Yet Sacramento Taxpayers Opposed to Pork, the group behind the ballot measure, insists it is a homegrown effort, aimed at giving voters a voice. Its leaders today vowed to come back fighting - possibly with a local fundraising effort.

Vucevic doesn’t compare to [Dwight] Howard athletically or on the defensive end — not by any stretch.

But he provides a more well-rounded offensive game than Howard did – the ability to shoot outside. Vooch also showed he can collect rebounds at a Dwight-like rate at times, finishing second in rebounding to Howard last season and mimicking Howard as a double-double machine.

Vucevic, the 76ers’ No. 16 pick in the 2011 draft out of USC, had a break-out season. He averaged 13.1 points and 11.9 rebounds after limited playing time as a rookie with the Sixers. He recorded 46 double-doubles – the third highest total in the NBA.

He exposed defending champion Miami’s lone weakness, feasting on the Heat’s soft interior with two 20-20 games, including a franchise-record 29-rebound performance.

A mandatory restraining order was issued after charges were filed surrounding a domestic violence incident, according to court records.

“They were yelling at each other and broke each other’s phones,” Robinson said. “I don’t believe it was physical otherwise.”
