League clears Giants regarding Eli Manning injury:

Did the Giants violate the injury-reporting rules by failing to disclose that quarterback Eli Manning had been suffering from plantar fasciitis, an inflammation of tissue in the bottom of the foot?

NFL spokesman Greg Aiello was asked that question and this was his response.

“We asked the Giants for an explanation. We accept the distinction between plantar fasciitis as an irritation that is not a reportable injury versus a sprain, strain, fracture, dislocation, or in this case an injured plantar fascia that is reportable.  As soon as the Giants took an MRI on Eli Manning’s foot and determined he had injured the plantar fascia, the team disclosed it publicly.  The injury report does not require the listing of every sore or irritated body part unless it is severe enough to affect the player’s ability to participate in practice or games.”

So the answer is no they didn’t violate the rules and they were cleared in the matter.
