Rajon Rondo is back on the practice court with his Boston Celtics, but he’s still a ways away from a return.

Rondo spoke to the media after the Celtics were routed by the Indiana Pacers Sunday and for the first time gave a vague timeline for his return, reports A. Sherrod Blakely at CSNNE.com.

“My endurance is key for me,” he told reporters after Boston’s 106-79 loss at Indiana on Sunday. “I don’t want to come back and not be fully 100 percent as far as my health and me being in shape as well. The worst thing for me is to not be in shape and have another injury. I want to make sure I’m in basketball condition shape.”

After initially telling reporters a January return was not realistic for his return, he later said that, “it might be mid-January, late February. I’m going to come back when the time is right and when I get my stamina.”

So the second half of January, or maybe February. Rondo is giving himself a big window — but he’s allowed to do that.
