There is still a chance that Orlando Magic star Dwight Howard could become a member of the Brooklyn Nets, according to league sources.

The Nets and the Magic are discussing a trade that would send Howard to Brooklyn for Brook Lopez, Kris Humphries, MarShon Brooks and the Nets' first-round draft picks in 2013, 2015 and 2017, sources said. Lopez and Humphries, who are both free agents, would go to Orlando in sign-and-trade deals.

No trade is imminent, and the Nets are looking for a third team to help facilitate a potential trade for Howard.

The Magic are also considering trade possibilities with the Los Angeles Lakers, Atlanta Hawks and Houston Rockets, sources say.

The Nets are trying to pull off their second blockbuster trade this week and give themselves a big three of Howard, Deron Williams, who agreed to terms Tuesday, according to sources, and Joe Johnson that could rival the NBA champion Miami Heat's heralded trio of LeBron James, Dwyane Wade and Chris Bosh.

In fact, the Nets would actually have a big four as they move into their first season in Brooklyn. Sources said that forward Gerald Wallace has agreed to a four-year, $40 million deal to stay with the Nets.

On Monday, the Nets agreed to terms with the Hawks on a trade that sends Johnson to Brooklyn for the expiring contracts of Jordan Farmar, Johan Petro, Anthony Morrow and Jordan Williams, plus DeShawn Stevenson and the 2013 first-round pick they acquired from Houston.
