Just a few days after suffering a facial fracture while playing against the Hornets, Celtics point guard Kyrie Irving is expected to return Tuesday against the Nets. Irving missed the Celtics' win over the Raptors on Sunday, but did participate in the team's shootaround Tuesday morning, according to ESPN. He told reporters that he plans to wear a face mask in Brooklyn. "It's gonna be pain tolerance, comfort with the mask," Celtics coach Brad Stevens said. "All that stuff — that's between him and our medical staff. He went through everything this morning."
