"I think this is the right decision," Pachulia said Saturday before the Hawks played Orlando. Atlanta Hawks center Zaza Pachulia will undergo season-ending surgery on his sore right Achilles. Pachulia had not played since a March 3 loss to the Lakers in Los Angeles, missing 15 games before deciding on surgery. He is set to become an unrestricted free agent at the end of the season and may have played his last game for the Hawks. The team already lost guard Lou Williams to a season-ending knee injury. Starting center Al Horford missed his second straight game due to an illness, while backup guard John Jenkins was out with a concussion.
