Dwyane Wade needs time to heal, and the Miami Heat saw no reason to further postpone the inevitable.
Wade will miss the remainder of the season so he can further rehabilitate his surgically repaired left knee, which has bothered him for about a year. He will undergo a powerful shock-wave treatment later this week, and hopes he will be pain free in time for next season.
Miami entered Monday's game with the Los Angeles Clippers with the NBA's worst record, 11-50. Arizona basketball coach Lute Olson is returning to the Wildcats at the end of the season. The 73-year-old coach has been on personal leave since Nov. 4.
Olson requested the leave for undisclosed personal reasons. Assistant Kevin O'Neill took over as interim coach, and in December the school chose O'Neill the permanent successor once Olson retired.
Olson is 780-280 in 34 seasons overall and 589-187 in 24 years at Arizona. He's led the team to 23 straight NCAA berths, the nation's longest active streak.
