Ariza has averaged 3.3 points and 2.2 rebounds in 11 games this season, his fourth in the NBA. Last season, he averaged 8.9 points and 4.4 rebounds for the Magic.

The 6-foot-8 forward left UCLA after one season and was drafted by the New York Knicks with the 43rd overall pick in 2004.

"He's a 6-8 athletic, active guy," Lakers coach Phil Jackson said before their game against the Indiana Pacers. "His specialty is probably defense. He's an all-around player, but defensively, with the athleticism — he's tough."

Cook has played sparingly this season for the Lakers, averaging 2.3 points and 1.7 rebounds in six games. He was in the first year of a three-year, $10.5 million contract.

The 6-9, 250-pounder was a first-round pick by the Lakers in the 2003 draft after playing at Illinois. He turns 27 on Dec. 4.

Cook's best season was in 2005-06, when he averaged 7.9 points, 3.4 rebounds and 19 minutes, all career highs.

Cook, along with Kobe Bryant, Derek Fisher and Luke Walton, were the only players on the current roster who played with the Lakers in 2003-04, the last time they advanced beyond the first round of the playoffs.

Evans averaged 4.4 points in seven games for the Lakers this season. The 29-year-old was in the final year of his contract.

The 6-5, 220-pounder averaged a career-high 8.4 points in 76 games last season, his first with the Lakers. Evans was acquired from Detroit in a draft day trade in 2006. He's also played for Minnesota and Sacramento.

"We gave up two players that were veterans, experienced players who fit into our system relatively well," Jackson said.
