EAST RUTHERFORD -- David Wilson might need more than a favorable doctor's visit Monday to continue his NFL career.

According to multiple sources, the running back, who suffered a "burner" during Tuesday's practice, months after undergoing spinal fusion surgery, is a long shot to return to the field. One person with knowledge of the running back's medical condition told NJ.com that Wilson "needs a miracle."

The source spoke on the condition of anonymity because he was not authorized to speak publicly on the matter.

That differs significantly from the always-sunny viewpoint of Wilson, who tweeted that "everything was fine" Wednesday night. The Giants, however, don't feel the same way, another source -- who requested anonymity to speak freely -- told NJ.com.

In the meantime, both sides will wait until Monday's examination for an official determination, although it sounds as if the Giants have come to grips with the seriousness of the condition and the possibility that Wilson's career is over.

Wilson will meet with Dr. Frank Cammisa, his first consultation with Cammisa since the burner. Cammisa, the doctor who performed Wilson’s spinal surgery in January, was not at the Hospital for Special Surgery on Tuesday, when Wilson was put though a battery of tests.

The Giants did their best to build a stable of running backs behind the 2012 first-round pick in case a setback occurred. The team always viewed Wilson's return this season as a bonus. Now, however, there's a good chance he will never return.

During initial testing in October, some in the organization feared that Wilson would not play another down. Given the nature of his position, and 100 percent guarantee that he would get hit in the neck or shoulders again, there was plenty of doubt.

Now, that same gloomy feeling is surrounding Wilson's appointment on Monday.

The Giants had hoped the lightning-fast Wilson would become a weapon -- especially in the pass game, but it never panned out. First came fumbling problems, then the neck injury last season, when he played in just five games.

In two seasons, he has rushed for 504 yards and five touchdowns. He has six receptions for 42 yards and another TD.
