Nicks underwent an MRI in Albany on Tuesday night, then left the team and traveled to Manhattan on Wednesday morning to undergo another MRI at the Hospital for Special Surgery, where team physician Dr. Russell Warren was able to examine the knee.
The Giants are relieved that their promising second-year receiver hasn't suffered anything major after enduring a season full of injuries last year.
Nicks injured his knee at the end of Tuesday's afternoon practice. Even though he was able to walk under his own power, he rode a cart from the field to the locker room.
Shortly after the injury and prior to the MRIs, a source said that the initial feeling about the injury was positive but nothing would be known until the tests results were in.
The Giants said Nicks, who was practicing once a day as he returns from offseason toe surgery, could return to practice as early as Thursday. The team did not practice Wednesday.
General manager Jerry Reese said the team wanted to be cautious with Nicks, who could start opposite Steve Smith, after seeing what happened to punt returner Domenik Hixon. Hixon tore his ACL during a June practice at the New Meadowlands Stadium.
The Giants' karma with injuries might be improving. They sent center Shaun O'Hara to the Hospital for Special Surgery to have his swollen left ankle examined Tuesday, and they got good news after an MRI revealed no further damage and a chronic condition in his joint.
