-- Rookie wide receiver John Dunlap joined the minicamp on a tryout basis. Dunlap, 6-1, 218, went undrafted out of North Carolina State in late April after catching 45 passes for 375 yards and three touchdowns.
Sparano said the team had evaluated him before the draft, and this would give the Dolphins a closer look at him while also allowing them to rest some of the receivers.
Sparano said he wants to see all three quarterbacks in all sorts of situations.
-- It's a similar scenario on the offensive line, where players continue to be shuffling from spot to spot.
Sparano indicated after the morning practice that third-year veteran Trey Darilek has played all five spots along the line this spring. Darilek lined up with the first-team offense at right guard in the morning practice, with free agent pick-up Justin Smiley going to left guard after working mostly on the right side.
-- Safety Yeremiah Bell revealed Saturday morning he took a one-year deal to re-sign with the Dolphins because he didn't think he would get a longer deal after missing all but one game last season with a torn Achilles.
Sparano praised Bell after the morning practice, but added that the Dolphins need to make sure they can get him on the field for a game, alluding to his all-out habits in practice.
-- Matt Roth still is lining up at left defensive end with the first defense, but he continues to get some work in some outside linebacker drills.
