Aaron Ross never got on the field last week against Peyton Manning and the Broncos as there were no snaps defensively for the Giants’ veteran cornerback. Now against the Panthers this week Ross likely will be not only playing on defense but starting. “I think we’ve all gone through that at some point in our career” Ross’ defensive backfield mate Antrel Rolle said. “We understand the nature of this business.” Ross is probably going through it this week. Starting cornerback Corey Webster did not practice on Friday for a second straight day due to a hip problem and is listed as doubtful for Sunday’s game against the Panthers in Charlotte N.C. Barring something unforeseen Ross figures to move from the bench to the starting lineup with Terrell Thomas remaining as the slot corner. Thus while last week was nothing for Ross this week is probably all. “I prepare like I’m a starter every week” Ross said. “No matter if I play or not.” Webster has been a model of durability through the last two-plus seasons playing and starting the last 38 games for the Giants in the regular season and playoffs. His loss would be significant for the 0-2 Giants especially as they prepare for a critical game against Cam Newton Steve Smith and the rest of the Panthers. The Giants’ secondary is banged up — they lost safety Stevie Brown in the preseason with a torn ACL they lost cornerback Prince Amukamara in Week 1 against the Cowboys with a concussion (when Amukamara was injured Ross was summoned) though he is now back and now Webster is ailing. All four starters in the secondary have dealt with a recent injury factoring in Rolle’s sprained ankle during training camp.
