Coach Joe Philbin Dolphins on the second-day of mini-camp.

DAVIE - John Jerry has battled weight issues his entire football career, from Pop Warner to the pros, and it appears his battle with the bulge continues in 2013.

Jerry, who has served as the Miami Dolphins starting right guard for two of his three seasons, claims he began the offseason program weighing under 340 pounds. But it appears he’s put on a few extra pounds during the three weeks Miami's OTA practice sessions.

Jerry is listed at 345 pounds on the team’s minicamp roster.

When asked whether Jerry is heavier than when the offseason program began coach Joe Philbin’s response was: “Not much.”

“He’s doing a good job,” Philbin said about Jerry, whom the coaches wants under 340 pounds. “He’s not much heavier.”

Jerry, a third-round pick in the 2010 draft, has spent every snap this offseason as the Dolphins starting right guard. But this former Ole Miss standout might have competition during training camp in July when Lance Louis, a free agent addition, is medical cleared to practice.

Louis tore the ACL in his left knee in late November while starting at right guard for the Chicago Bears. Louis, who has started 28 games for the Bears in his four seasons, is optimistic he’ll be able to practice with his teammates in a month or two.

Observations from Omar Kelly:

— New fullback Evan Rodriguez is wearing No. 48.

— Florida International's coaching staff is here visiting the Dolphins.

Randy Starks is getting pre-practice snaps with the 2nd team D-line, where he's paired with Kheeston Randall.

Richard Marshall has spent the past two days working as the nickel, returning to the role he held early in 2012.

— When Richard Marshall goes inside to play nickel Dimitri Patterson is the third cornerback who goes to the boundary opposite Brent Grimes.

— Again, Dolphins first-round pick Dion Jordan is the only player not here. He's not allowed to attend because of NFL rules.

Olivier Vernon has spent all of the offseason as the Dolphins starting right defensive end. Will it allow him to hold off Dion Jordan?

— I'm always fascinated that Brent Grimes goes through his stretching drill holding a football. Does it every day.

Jamar Taylor continues to work on the side. This gives fellow CB Will Davis an opportunity to entrench himself in the top 4.

Dustin Keller is holding a helmet, but I don't see him practicing with the team.

— Caleb Sturgis is kicking today. He just made a 47-yard field goal.

— Caleb Sturgis just split the uprights on a 48-yard field goal.
