Hip surgery has been ruled out for Celtics point guard Isaiah Thomas, president of basketball operations Danny Ainge said on Wednesday.

Ainge said that Thomas, who severely aggravated an injury to his right hip during Game 2 of the Eastern Conference finals, has resumed light on-court work and has been ramping up his cardiovascular training off the court.

“Isaiah is making good progress,” Ainge said. “He’s out on the court; he’s shooting. He’s full-speed ahead on the stationary bike and working in the swimming pool. He’s progressing nicely.”

Thomas originally injured the hip during the third quarter of the March 15 game against the Timberwolves and missed the next two games. The two-time All-Star aggravated the injury in Game 6 of the Eastern Conference semifinals against the Wizards, yet pushed on. But following the Game 2 loss to Cleveland a week later, the pain was simply too severe for him to continue.
