Phoenix Suns forward Grant Hill underwent an appendectomy Wednesday evening and will be sidelined at least two weeks.
Hill, 35, felt ill at the morning shootaround and was later hospitalized and scheduled for surgery.
He has started all 34 games this season, averaging 15.9 points, 4.6 rebounds, 3.5 assists, 1.0 steals and 33.9 minutes.
Hill signed with Phoenix last July 11 for two years and $3.8 million US, a modest sum compared to the seven-year, $93-million US contract he had with the Orlando Magic.
The seven-time all-star was expected to be the franchise cornerstone in Orlando, but missed roughly two-thirds of the Magic's game because of chronic ankle problems.
He has averaged 19.8 points, 6.8 rebounds, 5.2 assists, 1.4 steals and 36.8 minutes in 669 appearances, including 663 starts, over 13 NBA seasons with the Detroit Pistons, Magic and Suns.
Only two other active players, LeBron James of the Cleveland Cavaliers and Dwyane Wade of the Miami Heat, average at least 20 points, five rebounds and five assists.
Hill was drafted third overall out of Duke by the Pistons in 1994, and shared NBA rookie of the year honours with Jason Kidd.
He spent six seasons in Detroit before being traded to Orlando for Chucky Atkins and Ben Wallace on Aug. 3, 2000.
