The Houston Chronicle (Jonathan Feigen) reports: Seeking a break in his rehabilitation routine, Rockets center Yao Ming is visiting China this week with plans to return to Houston in time for the playoffs. “He’s done a stretch of his rehab,” John Huizinga, Yao’s NBA agent, said. “He has a long stretch of rehab coming up. This is a window of time. It’s an opportunity to take a break and get a change of scenery. He wants to be back to be with his Rockets teammates once he is off his crutches for the playoffs, and when that happens he will step up treatment too.”
