Rondo, who tore his right ACL last January and underwent surgery in February, did not give a specific date for his possible return.
"It's just a feeling," he said, according to MassLive.com. "I'll probably just wake up that morning and play."
Rondo said he feels "10 times better" and "more confident, stronger, more explosive" than he did when he was cleared to begin full-contact activities last month.
"In practice, when we have done 5-on-5 and he's been able to compete in that, he has really, really done well," said Celtics coach Brad Stevens, according to MassLive.com. "And part of that is because not only does he have a feel for where he should be, he just gets everybody else in the right spots."
Rondo confirmed that is still a possibility.
