David Wilson played in only five games this season before a herniated disk in his neck landed him on injured reserve and the uncertainty about his physical health led Giants general manager Jerry Reese to verbalize a serious concern.

“I don’t think you go into the next season saying David Wilson’s going to be our No. 1 starting running back,’’ Reese said Monday. “The guy is coming off of a neck surgery, if he decides to have it.’’

Reese said the Giants are “hopeful’’ Wilson can resume his NFL career. “The earlier reports that I’ve gotten, doctors do think they can fix this and he’ll be able to play,’’ Reese said.

But there are no guarantees. Wilson, the 2012 first-round draft pick, had a miserable start to his second season, losing two fumbles on opening night in Dallas and averaging only 3.3 yards on his 44 rushing attempts. Now he’s a medical risk.
