Miami Dolphins head coach Tony Sparano announced several key players were ready to fully participate when training camp opened Friday afternoon.
The Dolphins didn't place anybody on the active/physically unable-to-perform list. That means several notable players were cleared for practice.
Wide receiver Brandon Marshall had hip surgery in the spring and was unable to practice in the offseason.
Sparano didn't sound concerned about getting Marshall up to speed. Although Marshall couldn't take part in voluntary workouts or minicamp, he spent considerable time playing catch with and learning from quarterbacks Chad Henne and Chad Pennington.
"I don't think we're all the way caught up, obviously," Sparano said, "but I feel like we're pretty close."
Pennington had reconstructive shoulder surgery on his throwing arm and was limited in offseason workouts. Pennington will compete to be Henne's primary backup.
"He's progressed very nicely," Sparano said. "Chad is ready to go, and he'll get out there and get some reps."
Running back Ronnie Brown is recovered from a broken foot suffered in Week 10.
Running back Patrick Cobbs is returning after a season-ending knee injury in Week 5.
Cornerback Will Allen is coming back from a season-ending knee injury in Week 7.
