He is scheduled to see another doctor in Alabama tomorrow. May's agenda after that is unknown, as his two-year struggle to get healthy seems without end. First-year coach Sam Vincent had no timetable for May's return.

"I think he's getting a second opinion, or maybe a third opinion," Vincent said. "We're hoping at some point he's going to gather up enough information to know exactly what the next step should be."

May, taken by the Bobcats with the 13th pick in the 2005 draft, has played in only 58 of 164 games in his first two seasons because of right knee pain. He had surgery to remove cartilage during his rookie year, then developed a bone bruise in the knee last season.

In March, former coach Bernie Bickerstaff challenged May to lose weight, insinuating May's injury woes were due in part to being in poor shape.

May vowed to go on a rigorous offseason conditioning program, but the knee remains a concern. One of his stops will be in Birmingham, Ala., to see orthopedic surgeon Dr. James Andrews.

"I don't think he had a setback," Vincent said. "He was working out over the summer. He was doing some good stuff. He was playing. I think now, before he goes to the next step of really having to push it for training camp, everybody just wants to make sure that the knee is healthy enough to do that."

Point guard Raymond Felton, who teamed with May to help North Carolina win the 2005 national championship, said today he's confident May will return.

"I'm definitely not concerned about him," Felton said. "Sean is fine."

When healthy, the 6-foot-9 May has been effective in the NBA and has slowly extended his shooting range. He's averaged 10.4 points and 5.9 rebounds, and scored 32 points off the bench against Orlando in December.
