Los Angeles Dodgers left-hander Julio Urias will not come off the injured list for his scheduled start on Sunday after feeling discomfort in his strained left hamstring, manager Dave Roberts said Friday.

Urias suffered the setback during a bullpen session Thursday and will miss at least another week or two, Roberts said. Urias had been slated to start Sunday against the Philadelphia Phillies after being out since May 18.

"He's going to keep throwing," Roberts said. "But I think when he tries to ramp up the intensity is when he sort of feels the tightness in the hamstring."
