Bo Jackson probably has played his last game, in baseball or football, people with knowledge of Jackson's injured hip told two newspapers.

"The cartilage has sort of wasted away" since the football injury Jackson suffered in the NFL playoffs and the damage it caused is worse than initially thought, a source told the The Washington Post in Thursday's editions."In reality, he has an old man's arthritic hip," the source said. "There is no question: He will not play professional sports again."

Meanwhile, an orthopedic specialist who recently examined Jackson was quoted in today's Los Angeles Times as saying Jackson's athletic career is almost certainly finished.

Asked if Jackson could return to the Los Angeles Raiders, the doctor, who requested anonymity, said: "No. I don't think he'll play for anybody. I don't see how he can. It will be too painful."
