The Indiana Pacers announced Saturday that they signed free agent center Andrew Bynum to a contract for the rest of the season.

The team did not release terms of the deal. Bynum, 26 will join the Pacers, who have the best record in the Eastern Conference at 35-10, sometime next week and serve as a backup to All-Star center Roy Hibbert.

The Pacers had an open roster spot and $2.1 million left of their midlevel exception, according to ESPN. But they are about $1.8 million below the luxury-tax threshold and president of basketball operations Larry Bird has said the team does not want to pay the luxury tax.

Bynum played in 24 games for the Cleveland Cavaliers earlier this season and averaged 8.4 points and 5.3 rebounds before he was traded to the Chicago Bulls on Jan. 7 because of issues that led to a team suspension. The 7-footer was then waived by the Bulls in a salary-saving move.

Stern retired exactly 30 years to the day he began his stint as the NBA's longest-tenured and most successful commissioner. Silver joined the NBA as Stern's assistant in 1992 and became deputy commissioner in 2006.

---Oklahoma City Thunder guard Russell Westbrook is targeting Feb. 20 to come back from arthroscopic surgery on his right knee, according to Yahoo! Sports.

Westbrook has been out since late December and was expected to be out through the All-Star break. The All-Star Game is Feb. 16 and the Thunder return from the break on Feb. 20.

Westbrook sustained a torn lateral meniscus in his right knee during the second game of the NBA playoffs last April. He had surgery on April 27 and another operation on Oct. 1 to remove a loose stitch from the first procedure. He returned to action ahead of schedule and ended up missing just two regular-season games.

Westbrook averaged 21.3 points, 7.0 assists and 6.0 rebounds per game in 32.9 minutes as the Thunder won 23 of their first 28 games of the season before the injury.
