Three Chicago men were charged in the shooting death of the brother of Knicks G Quentin Richardson yesterday.

Lee Richardson Jr., 31, was shot outside the family's Chicago home Monday during a robbery, police said. His father, Lee Richardson, Sr., 62, was with him at the time but was not injured, family members said.

Elbert Dunnigan, 24, and Ishmael Clark, 29, were charged with one count each of first-degree murder and armed robbery. Clark also was charged with three counts of attempted murder of a police officer.

A third Chicago man, Gino Wilson, 18, was charged with one count of first-degree murder and two counts of armed robbery. He also was being held on a Kankakee County murder warrant, police said.

The Knicks said Quentin Richardson, 25, left the team Monday to return to Chicago for a family emergency. It is uncertain when Richardson will come back.

* NO MORE TESTING DURING GAMES: Players will not be allowed to take drug tests during games, the league said, after a SuperSonics player missed part of the third quarter Tuesday night while taking his.

NBA spokesman Tim Frank would not talk specifically about Seattle starting F Reggie Evans, who teammates said missed the first few minutes of the second half of a 104-101 loss against the Knicks while being tested.

"Our policy . . . does not require a player to take a drug test at any point during a game, and we will ensure going forward that no testing is conducted during this time," Frank said.

Said Evans: "I'm cleaner than clean. I'm cleaner than Pine-Sol."

* SURGERY FOR WILLIAMS: Raptors G Alvin Williams is out indefinitely after he underwent arthroscopic surgery on his right knee this week in Birmingham.
