Jones has achilles and calf injury

SNY NFL insider Adam Schein is reporting that Jets tailback Thomas Jones had an achilles injury that led to his calf strain.

"A source close to Thomas Jones tells me that the orginal injury the running back had was an achilles strain, and as a result of favoring that injury, one week ago in practice, he suffered a calf strain," said Schein on SNY's Geico Sportsnite. "The same source did tell me, Adam, he will be ready for the New England Patriots game in Week One. Achilles strains can linger thoughout the course of a campaign. So it was an achilles strain that morphed into a calf strain."
