The New York Giants are unsure if David Wilson be able to play for them again.

The source said it would take some unexpectedly good news from Wilson's surgeon on Monday to convince the Giants that it's OK for their 2012 first-round pick to return to action.

According to another source close to the situation, Wilson has been very upbeat and has told people he'll be fine again after a couple of days off. His teammates backed that up in conversations Thursday.

"It was good to see him back in the meeting room, bright-eyed and ready to go," fellow running back Rashad Jennings said.

David Wilson underwent a battery of tests on his neck Tuesday night and will not practice until at least next week.

Wilson, who left Tuesday's practice with what coach Tom Coughlin called a "burner," will be evaluated by Dr. Frank Cammisa at the Hospital for Special Surgery on Monday. He will miss Sunday's preseason opener against Buffalo.

Wilson was a first round pick by the New York Giants in 2012 and was expected to split carries with Rashad Jennings.

Brill Barnwell has released his 2014 NFL Trade Value rankings, headlined by Russell Wilson at No. 1 and Andrew Luck at No. 2.

Wilson is ranked ahead of Luck because he is still two years away from being paid market value.

Aaron Rodgers is ranked No. 3, though Barnwell writes that he would rank him as the most talented quarterback in the NFL right now. But Rodgers is 30 and makes far more money than younger, cheaper quarterbacks.

J.J. Watt is the first defensive player on the list and ranks No. 4.

Colin Kaepernick and Cam Newton are ranked No. 5 and No. 6 respectively. 

Robert Quinn is at No. 7 as the second-highest ranked defensive player.

Peyton Manning, Matt Ryan, Drew Brees and Tom Brady rank No. 8-No. 11.

12. Patrick Peterson

13. Earl Thomas

14. Richard Sherman

David Wilson had an MRI exam on Monday on his neck and he's been cleared to play football again.

Wilson is expected to play a change-of-pace role behind Rashad Jennings.

Wilson was a first round pick in the 2012 NFL Draft.

Chris Snee is likely to retire at the age of 32.

Snee has undergone two hip surgeries and an elbow surgery over the last two years. He has reportedly been slow to recover from the elbow surgery, which prompted this decision.

Snee was a four-time Pro Bowler and one-time first-team All-Pro in his career at guard with the New York Giants.
