The Miami Dolphins continue to mix and match in the middle of their offensive line.
For the second consecutive day, starting center Mike Pouncey took snaps at right guard with the first-team offense at practice Sunday. Pouncey started every game at center for Miami the past two seasons after joining the team as a first-round draft pick in 2011.
Second-year player Josh Samuda took Pouncey's place at center during drills when Pouncey was at right guard. Richie Incognito, a Pro Bowl selection as a left guard in 2012, lined up on both sides with the first-team offensive line.
The Dolphins, who open their five-game preseason schedule next Sunday against the Dallas Cowboys in the Hall of Fame Game, began shuffling their offensive line Friday after 2012 starting right guard John Jerry was sidelined with an undisclosed injury.
