The Sacramento Kings voided Chuck Hayes' $21.3 million, four-year contract Monday, saying the forward-center failed a team physical that forced his release.

Kings general manager Geoff Petrie said in a statement that informing Hayes his deal had been voided was "one of the most heartbreaking moments of my professional or personal life." He said Hayes asked the team to refrain from any further comment.

The team announced last week that a heart exam on the new Kings big man showed an abnormality that would require further testing. That came days after the former Houston Rockets forward-center signed a contract with Sacramento.

Hayes, now 28, averaged 3.4 points and 4.7 rebounds in 17 minutes per game in six seasons with the Rockets.

Davis signs

Baron Davis' desire to play in New York outweighed the chance to play with Kobe Bryant or LeBron James.

The veteran point guard signed with the Knicks, passing up a chance to join stronger teams because he said he always saw himself playing at Madison Square Garden.

"I always kind of rise to the occasion when I'm playing against the Knicks and playing in the Garden," Davis said at the Knicks' training facility. "It's just an unbelievable opportunity and I'm ready to accept the challenge."

Biyombo a Bobcat

Forward Bismack Biyombo signed a rookie contract with the Charlotte Bobcats hours after agreeing to pay a buyout clause to release him from his contract with Spanish club Fuenlabrada.
