"The Braves left-hander injured his right hamstring in the first inning of his first start in the Mexican Winter League last week. He left after one inning, and it’s uncertain if he’ll pitch again this winter."

“We don’t know when he’ll come back [in winter ball], if at all,” Braves general manager Frank Wren said. “There’s only four weeks left in the season, and hamstring injuries usually take a while.”
