Ricky Rubio said he tested positive for COVID-19, which delayed his arrival to the bubble.
Rubio participated in his first practice on Tuesday.
The Suns will have their first scrimmage on Thursday, though it's unlikely that Rubio will participate.
"I feel good but we have to be smart about it. It's a preseason game. We have to figure out a plan that's day by day. We can't plan ahead like other times. We didn't know when I was going to come so we have to play it day by day," said Rubio.
Monty Williams said he will determine Rubio's playing status moving forward on Wednesday.
