ARAUJO VOLUNTEERING: Jazz and ex-BYU center Rafael Araujo will join other current and former NBA players in serving this summer as a camp coach for youths at the league's Basketball Without Borders program in his native Brazil.

Sao Paulo is one of four locales for the NBA camp this year, along with Paris, France; Shanghai, China; and Johannesburg, South Africa.

ALUMNI UPDATE: With both Luke Ridnour and Earl Watson out with sprained left ankles, Seattle on Wednesday signed ex-Jazz guard Randy Livingston from Idaho of the D-League to back up Mike Wilks at the point for the Sonics' final four games of the season.

"Injuries have left us with a substantial hole in our guard rotation and we were fortunate to find a guy out there like Randy, who has some NBA experience," Sonics general manager Rick Sund said in a statement released by the team.

Livingston, who played 17 games for the Jazz during the 2004-05 season, has been with nine different NBA teams in 10 seasons. This is his second stint in Seattle. He averaged 12.3 points and a league-high 10.6 assists for Idaho, the D-League affiliate of Utah and Seattle.

ALUMNI UPDATE II: According to the Tacoma (Wash.) News Tribune, former Jazz forward and current Phoenix assistant coach Marc Iavaroni's name has "surfaced" as a possible replacement for Seattle coach Bob Hill should Hill be relieved of duties after the season."

Iavaroni also has been mentioned as a candidate for jobs in Memphis and, should it open up, in Toronto.

QUICK QUIZ: With the Jazz retiring Adrian Dantley's old No. 4 uniform number Wednesday, which other ex-Jazz players wore 4? Answer: Kenny Boyd and Fred Boyd before Dantley, and Kelly Tripuka for two seasons after Dantley.
