Keith, who has been cleared for contact in practice, skated on his own Tuesday at United Center and will be a full participant in practice Wednesday.
"He's skating well, moving well, feels good," Quenneville said. "We'll see how he is [Wednesday], with some guys on the ice. He feels good so we'll see what happens at the end of the week."
After playing the New Jersey Devils on Thursday, the Blackhawks play Saturday at the St. Louis Blues and Sunday at home against the Calgary Flames. Keith is eligible to be activated off long-term injured reserve Saturday.
