That would set his return to sometime in the middle of September.
"I'm encouraged with how everything is progressing," said Lowrie, who has been working out in Houston. "I'll just continue to take each step, jump through every hoop and make sure it's good to go and get back out there as soon as possible."
He said he is starting to feel more confident on the knee, which is still being supported by a brace.
"We're just going to continue to find new things to do and new ways to push it to make sure that that confidence continues to build without pushing it too fast where I could potentially hurt it again," Lowrie said. "It's kind of that balance."
Lowrie's injury happened during a collision at second base against the Giants on July 14.
