ATLANTA -- Right-hander Jair Jurrjens, his future with the Braves in doubt, will begin a rehab assignment with Triple-A Gwinnett, which returns home on Monday for an eight-game homestand.
"All I know is that I'm going out," Jurrjens said Sunday. "I don't know when I'll pitch."
Jurrjens was put on the disabled list Thursday to clear a roster spot for starter Paul Maholm, who was acquired in a trade with the Cubs before the Trade Deadline.
Jurrjens hurt his right groin on Tuesday against Miami as he made his first relief appearance after being demoted from the rotation.
"I slipped and it was tight the next day," Jurrjens said. "Now it feels OK."
Jurrjens was 13-6 with a 2.96 ERA last season and made the All-Star team. But he suffered a knee injury late in the season and has struggled mightily this year.
The right-hander was demoted to Gwinnett in late April after four starts and didn't return until late June.
He pitched well in his first game back at Boston and won his next two decisions as well. But he lost his spot again after being hammered in his next two outings, giving up 14 earned runs in 5 2/3 innings.
Jurrjens is 3-4 with a 6.89 ERA in 11 games.
