EAST RUTHERFORD, N.J. (AP) — Cam Skattebo is not practicing with the New York Giants after experiencing a setback, fellow rookie Beaux Collins has also been sidelined by an undisclosed injury and standout left tackle Andrew Thomas has yet to make an appearance on the field at training camp after landing on the physically unable to perform list. While there is still a month to go before the NFL season begins, the injuries are starting to pile up for the Giants on offense. Skattebo, their fourth-round pick out of Arizona State who was expected to be part of the running back rotation, was among those not participating Monday because of a hamstring injury.
