Outside linebacker Brian Burns, cornerback Dru Phillips, and safety Beau Brade were among those who either didn’t practice or, as was the case with Phillips, left practice early with an injury. Burns’ absence gave fellow outside linebacker Kayvon Thibodeaux, who had been mostly working with the second-team defense, a chance to work with the first-team unit. Phillips, the team’s top slot cornerback, was injured during the practice, with the consensus being something with his right leg. Giants running back Cam Skattebo, who is back from a season-ending ankle injury, has been having his workload monitored, Harbaugh revealed. In the meantime, the Giants will be at The Greenbrier through Saturday before getting a day off.
