Andrew Bynum missed the Indiana Pacers' win over the Philadelphia 76ers on Monday after undergoing an MRI due to swelling in his knees.
The Pacers expect to know more about Bynum's status in the coming days.
"This is what we signed up for," Frank Vogel said. "We knew he was a great player with some problem-area knees, (who was) going to be in some times and out some times.
"We're fully aware of that and we'll be excited whenever we have him in uniform."
