Lowrie has been undergoing daily rehab in Houston and has been wearing a brace to limit the mobility in his knee, though it's getting better. While the ankle has healed, Lowrie has a ways to go before being game ready. He was examined by a doctor Wednesday.
"I think it will certainly be by the end of the year, and as far as when specifically, I think it's a moving target just because it's a really atypical injury and there's not a lot of precedent on a hard timeline," he said. "I think would make it a lot easier if there were, but there's not."
Lowrie has been taking his rehab slowly, beginning with just an hour a day before progressing to more intense reps on his leg to make it stronger.
"I guess I'm pretty optimistic, so I always thought that there was going to be an opportunity to come back this year, but I don't know what internally they're saying about it," he said. "I always felt like with no structural damage, and since it happened only a couple of days after the All-Star break, I had time to get it right and play the last few weeks of the season."
