He opened Verizon Vikings Training Camp Sunday on Loadholt’s left side at right guard.
Harris said coaches let him know the plan near the end of Vikings organized team activity practices last month.
“It’s a great opportunity going in,” Harris said after the team’s first walk-through. “I haven’t played a lot of guard, but I feel like with each practice I’ll just improve.”
Harris was claimed by the Vikings last August after spending the first two-plus seasons with San Diego, including nine starts in 2012 when Vikings Offensive Coordinator Norv Turner was head coach of the Chargers.
