The Lakers have traded guard Sasha Vujacic and their 2011 first round pick to New Jersey for Joe Smith, Golden State’s second round pick in 2011, Chicago’s second round pick in 2012 and the rights to Ukraine’s Sergei Lishouk.

The deal is contingent on both Vujacic and Smith passing physicals. Lakers team spokesman John Black said that the team plans to put Smith through a physical in Philadelphia in advance of L.A.’s Friday evening game against the 76ers, and if he passes, he’ll be eligible to play in that contest.

The trade was finalized early on Wednesday morning, since Dec. 15 was the first day offseason signees like Smith could be traded. Houston was also involved in the three team trade, and principally received Terrence Williams from the Nets.

Vujacic, drafted by the Lakers back in 2004 out of his native Slovenia, won two championships with the Lakers and had his best season in 2007-08, when he played 17.8 minutes per game to score 8.8 points while shooting a still-team-record 43.7 percent from three-point territory.

Vujacic said he was given a heads up about the potential trade after L.A.’s Tuesday night victory in Washington, but said he "did not know what to say at the moment” as nothing was yet official. He had been playing only 4.9 minutes per game in the 10 games in which he appeared this season, lost in the guard rotation behind starters Kobe Bryant and Derek Fisher and subs Steve Blake and Shannon Brown. Vujacic will join fellow former Laker Jordan Farmar with the Nets.

Smith, the No. 1 pick in the 1995 draft, will be joining the 13th team of his 16-year career. He appeared in four games this season for New Jersey, playing a total of 24 minutes to score two points with three rebounds, and is considered a strong locker room presence.

Lishouk, 28, was originally selected with the 44th overall pick in the 2004 NBA Draft by the Memphis Grizzlies, and his rights were traded to Houston on February 21, 2008. A 6-11.5 center, Lishouk is currently playing for Valencia in Spain.

Per Lakers team policy, the terms of the trade were not disclosed.
