The Dallas Mavericks announced the signing of free agent forward DeJuan Blair on Wednesday.Terms of the deal were not announced but it is reportedly a one-year contract for the veteran’s minimum salary of just below $1 million.The 6-foot-7, 270-pound Blair was the 37th overall pick in the 2009 NBA Draft, taken by the San Antonio Spurs in the second round despite not having any anterior cruciate ligaments in his knees, the result of various surgeries in high school.The former Pitt All-American has averaged 7.8 points, 5.8 rebounds and 18.9 minutes in 288 career NBA games, including 166 starts, all with the Spurs.Blair has two career 20-point, 20-rebound games. One was April 14, 2010, against Dallas when Blair finished with 27 points and 23 rebounds.Rookie sent homeMinnesota Timberwolves rookie guard Shabazz Muhammad was sent home from the NBA’s annual Rookie Transition Program for a rules violation.According to USA Today, Muhammad, the 14th pick in the June draft, had a female guest in his hotel room Tuesday evening. Only hours before he was dismissed, players were given the rules for the program, which included no guests unless approved by program administrators.Muhammad, who left UCLA after his freshman season, will be fined and have to return next summer and complete the four-day program that helps rookies transition into the league through a series of seminars, instructions and guest speakers.In 2008, Mario Chalmers and Darrell Arthur were expelled from the rookie program after women and the scent of marijuana were discovered in their room. Michael Beasley later admitted he had been in the same room. All were fined.Oden joins HeatGreg Oden has taken his physical, done a bit of house hunting in South Florida and signed on the dotted line. Nearly four years after he last played, he’s officially back in the NBA. The former No. 1 overall pick signed his contract with the two-time defending NBA champion Miami Heat on Wednesday, the last in a series of formalities that needed to be completed before the team could finally announce the move. Oden said late last week that he was accepting Miami’s offer, one that will pay him about $1 million this coming year and includes a $1.1 million player option for the 2014-15 season. “I am very excited and happy to be here,” Oden said. “I’m thankful to the Miami Heat organization for bringing me in and I’m ready to get to work.” Heat president Pat Riley said Wednesday that the team will take a cautious approach with Oden, who has been through the cartilage-repair procedure known as microfracture surgery three times. Riley said the team spent “many months” getting to know Oden, both on and off the court. And when he decided to accept Miami’s offer — there were about a half-dozen serious suitors in all for the 7-footer, including the Dallas Mavericks — Oden said he was won over in part by how the Heat will not have the expectations for him to play big minutes right away. Oden’s last NBA appearance was Dec. 5, 2009, for Portland against Houston. Blazers add WilliamsGuard Mo Williams has agreed to a two-year, $5.6 million deal with Portland.
