Oher was selected in the first round in the 2009 draft after playing at left tackle in college for Ole Miss, but he has switched between the two sides of the line since joining John Harbaugh's team.
He told the Baltimore Sun: "I prefer playing right tackle. I've flip-flopped back and forth ever since I got here and played both sides, but I think right tackle is my best position.
"I think I'm better over there and the team is better with me over there."
Oher was part of the Ravens side that won Superbowl 47 in New Orleans in the 2012 season.
