Ross has been out all week with plantar fasciitis and has had his swollen right heel in a cast.
Coach Tom Coughlin initially said that Ross' plantar fasciitis did not involve any tear following Wednesday's afternoon practice. But after receiving the latest report from the team's medical staff, Coughlin was informed there was a tear on Wednesday night.
The team said the tear does not change Ross' initial prognosis. He will remain in the cast for 7-10 days -- which will likely keep him out of the remaining two preseason games -- and then will work on "his strength and modality." The team will reevaluate Ross afterward.
Antrel Rolle somewhat feels Ross' pain.
Rolle, a safety, suffered a complete tear of his plantar fascia last season playing against the Giants while with the Cardinals. He continued to play with the injury.
"Actually, his is a little bit different than mine," Rolle said. "He has plantar fasciitis, which is a partial tear. I tore my plantar fascia completely. To tear it completely is actually better than to tear it partially. Once you tear it completely, it kind of takes care of itself and it doesn't matter. Just depends on how much pain you can play on."
The Giants said plantar fasciitis does not automatically mean there is a tear.
Ross, who hasn't been in the locker room the past couple of days when the media was allowed in, recently traveled to Charlotte to visit a specialist. Ross suffered a hamstring injury in camp last year and played in four games last season. He had played well in camp and was happy to be healthy until injuring his foot last Saturday against the Pittsburgh Steelers. Ross is competing with Terrell Thomas for the starting cornerback spot opposite Corey Webster and was emerging as the team's punt returner as well.
Eli Manning played with plantar fasciitis last season but dealing with it as a quarterback is different than playing on it as a cornerback with all the cutting and stopping and running.
Rolle did not undergo surgery for his injury last season but he said his foot still feels stiff in the morning when he wakes up. Once he loosens it up, Rolle said he feels better.
"It's going to be something that he's going to have to deal with for a long time," Rolle said.
