Richard, a second-year center from Florida, appeared in five games last month for the Bulls, averaging 2.2 points and 4.6 rebounds.
"We're going to bring Chris Richard back and bring another big guy back, hopefully [Wednesday]," Bulls head coach Vinny Del Negro said after practice Tuesday. "But we need our guys to get healthy. One guy's not going to control the glass for us. I think it's going to help. Chris did a good job when he was here. He knows what we're doing. He's a good kid. So we'll get him back in here [Wednesday]."
