New Jersey Net backup center Jim McIlvaine had shoulder surgery Tuesday in East Rutherford, N.J., and will likely miss the rest of the season.
The team estimated he will require 3 1/2 months for rehabilitation.
McIlvaine had not played since March 17, and was put on the injured list five days later.
The Nets acquired former Temple center William Cunningham last week to replace McIlvaine on the roster.
McIlvaine played 22 games this year, averaging 2.2 points, 2.5 rebounds and 1.5 blocks a game.
The 7-foot-1 center joined the team in January from the Seattle SuperSonics in a trade for center Michael Cage and forward Don MacLean.
Sacramento King forward Chris Webber sat out Tuesday’s game against the Utah Jazz, his second consecutive absence because of flu.
Webber spent Sunday night in a Sacramento hospital getting intravenous fluids after suffering from dehydration. He returned home Monday.
Webber is averaging 20 points and leads the league in rebounding at 13 per game.
Denver Nugget rookie Keon Clark was taken to a hospital in Vancouver, Canada, as a precaution to have his chest X-rayed after an examination revealed a shortage of air entering his lung.
Clark complained of discomfort in his left chest when he arrived for Tuesday’s game against the Vancouver Grizzlies. Clark’s missed the game and his status will be determined after further examination.
