The Braves have moved Jurrjens' scheduled first start back to at least April 6 in Milwaukee and that may prove to be optimistic. If Jurrjens isn't ready, he could be put on the disabled list.
"He's progressing well. We're just not there yet," Wren said. "We're not pushing it, because we don't want to set him back."
Jurrjens is expected to get back on the mound and throw a side session soon.
"He played a little long catch today and that's about it," Braves manager Fredi Gonzalez said. "Hopefully, we get him on the mound here in the next couple of days."
