CLEVELAND — Cleveland Cavaliers rookie forward Darnell Jackson is out indefinitely with a fractured left wrist.

Jackson, who played in Cleveland's first four exhibition games, first told the team on Tuesday the wrist was bothering him. He played 11 minutes in Thursday night's game against San Antonio, and an examination on Friday revealed the fracture. Jackson said the wrist will be in a cast for about 10 days.

"I really don't know (how the injury occurred)," Jackson said. "Every time I taped it up, it felt fine. I can take a lot of pain. I finally asked them if they could check it out."

Jackson, who helped Kansas to the national championship last season, was selected in the second round by Miami. The Cavaliers acquired him for a 2009 second-round pick.

The 6-foot-8, 250-pound Jackson was averaging 3.5 points in the exhibition season. He was 7-of-11 from the field and had nine rebounds.

"He's had a good camp," Cleveland coach Mike Brown said. "Now, he has to figure out the other side of it, to stay in shape and keep learning."

Jackson, 23, averaged 11.2 points and 6.7 rebounds in 35 games for Kansas last season.

CAVALIERS' WILLIAMS TANGLES WITH 76ERS' MILLER: Cleveland Cavaliers guard Mo Williams was ejected Saturday night in the first quarter of a game against Philadelphia.

Williams, who formerly played for the Utah Jazz, and 76ers guard Andre Miller, a former University of Utah standout, were assessed double technicals at the 6:27 mark. Williams drew an offensive foul from Miller, who tossed the ball on the Cleveland player while he was on the floor. Williams quickly walked toward Miller before being stopped by teammates.

On Cleveland's ensuing possession, Miller fouled Williams as he drove to the basket, knocking him to the floor with 6:08 left. Williams said something when he got up and was ejected by referee Sean Corbin. It was unclear whether Williams was talking to Miller or Corbin.

Coach Mike Brown planned to play his starters into the second half. Williams, a key offseason acquisition from Milwaukee, will start at point guard and is expected to provide vital help for LeBron James.

WEATHERSPOON, FORMER ILLINI STAR AND NBA PLAYER, DIES: Nick Weatherspoon, a former University of Illinois basketball star who played seven seasons in the NBA, has died. He was 58.

The university said in a news release Saturday that Weatherspoon died in his hometown of Canton, Ohio, on Friday. The cause of death wasn't immediately known.

Weatherspoon left Illinois after the 1972-73 season as the school's career scoring leader with 1,481 points — still the 10th best in Illini history.

The 6-foot-7 forward was a member of the NBA's all-rookie team in 1973-74 and played for Washington, Seattle, Chicago and San Diego. He had his best season for San Diego in 1978-79, averaging 13.8 points in 82 games. He averaged 9.0 points in 453 regular-season games and 9.1 points in 31 playoff games.
