"He went to get a bone scan on his foot, but he felt pretty good this morning," Bulls coach Vinny Del Negro said. "Obviously, he didn't play a lot [Wednesday] night so we'll see what the results are.
"It's going to be a monitored thing every day. Depending on how he feels, and then therapy and just see how it works out."
Noah, who turned 25 on Thursday, played just seven minutes in Wednesday's 120-110 win over the Indiana Pacers.
He's been suffering from the injury for more than a month and recently missed seven consecutive games to rest the foot.
"The birthday's been good," Noah said. "I went to go get treatment. I went to go get X-rays; hung out with some doctors. It was pretty cool. Missed practice. A good day so far. At least it's nice outside.
"I'm hurting, obviously. But, it's the end of the season right now and I want to be there for my team, and I want to be as ready as possible come playoff time."
The Bulls host the Portland Trail Blazers on Friday night.
NOTE: Luol Deng sat out most of practice with a swollen left knee.
