Glen Davis will undergo surgery to repair a fractured fifth metatarsal in his left foot.
Davis is expected to miss eight to 12 weeks, which could effectively end his season.
Davis suffered the injury on Wednesday when he appeared to step on the foot of Iman Shumpert.
“I feel really bad for the guy,” J.J. Redick said. “I know he’s had high expectations for himself and for this team this season, and he’s had a rough go of it. I feel bad for him.”
