New York Knicks forward Rasheed Wallace will need surgery to repair a broken left foot and doctors expect him to miss the next eight weeks of the NBA season, the team announced on Wednesday. Wallace, a 38-year-old big man who came out of retirement to join the Knicks this season, has not played since December 13 and figures to miss the remainder of the regular season and start of the NBA playoffs with the fracture. In 20 games, Wallace averaged 7.2 points and 4.2 rebounds for the Knicks. The four-time NBA All-Star won an NBA title with Detroit in 2004. Wallace has averaged 14.4 points, 6.7 rebounds, 1.8 assists and 1.3 blocked shots in 1,108 NBA games over 15 seasons with Washington, Portland, Atlanta, Detroit, Boston and the Knicks.
