One day after a doctor told Adam Jones that his neck injury could end his career, another doctor delivered far cheerier news and cleared the Dallas Cowboys cornerback to resume playing in a few weeks, a league source said Wednesday.

The doctor determined that Jones had fluid in his spine but no injury that would require surgery.

If Jones isn’t placed on the season-ending injured-reserve list, he’s hoping to resume playing in the postseason — if Dallas can make it there.

It’s quite the reversal for a player whose career has been filled with them. But Jones is much happier with this information than the bit he got Tuesday. Once Jones heard the good news, he canceled the visit he had scheduled with a neck specialist in North Carolina.
