Rush showed great potential at times, but also found trouble. He was suspended for five games last season for violating the league's substance abuse policy.
Amundson has averaged 4.1 points and 3.7 rebounds in five seasons, primarily with Philadelphia, Phoenix, and Golden State. He has shot 52 percent from the field for his career.
Davis goes with Knicks
Point guard Baron Davis will sign with the New York Knicks, a source with knowledge of his plans told the Associated Press on Sunday. ESPN.com first reported Davis' intentions. Davis is expected to sign Monday, the source said.
Davis was waived last week by the Cleveland Cavaliers and designated as their amnesty player. He was not claimed and chose the Knicks, who are seeking more backcourt depth after waiving Chauncey Billups with the amnesty clause. New York had already signed another veteran point guard, Mike Bibby.
It's unknown when Davis will play as he's been sidelined all preseason by a bulging disk in his back. But he'd be worth the risk if healthy.
"Everybody knows what he can do when he's healthy and when he's focused," Knicks forward Carmelo Anthony said earlier Sunday, recalling a loss to Davis and the Cavaliers last season. "When BD is healthy, he's one of the best."
But he wasn't needed in Cleveland after the Cavaliers won the draft lottery and took Kyrie Irving with the No. 1 pick. By making Davis their amnesty player, the Cavs knocked the $28 million he was owed over the next two seasons off their salary cap.
Kings claim Outlaw
The Sacramento Kings have claimed forward Travis Outlaw off waivers under the NBA's new amnesty provision, filling out the frontcourt with another veteran.
The Kings announced the move Saturday night before opening the preseason at the Golden State Warriors.
The 6-foot-9, 207-pound forward was waived by the New Jersey Nets on Wednesday. Outlaw averaged 9.2 points and four rebounds in 28 minutes per game last season, making 55 starts. Outlaw is entering his ninth NBA season. He also has played for Portland and the Los Angeles Clippers. Outlaw has averaged 9.5 points, 3.5 rebounds in 22 minutes per game.
The new amnesty clause the Nets used on Outlaw allows teams a once-a-year-option to wipe a player's remaining contract from the salary cap and avoid any luxury tax penalties.
