DAVIE, Fla. -

Mindful that playing for the Miami Dolphins has its ups and downs, center Samson Satele is back.

He was a rookie starter with the Dolphins in 2007, when they went 1-15. He also started every game in 2008, when they were division champions and went 11-5 -- their most recent winning season.

Satele was then traded away, and now he's back after signing as a stopgap solution at the Dolphins' troubled center spot.

The Dolphins signed Satele on Saturday after their first training camp scrimmage, an indication they're unhappy with the other candidates to fill in for injured Pro Bowl center Mike Pouncey. Satele lined up with the first team when he practiced for the first time Monday, and he predicted he'll be ready to start Friday's exhibition opener at Atlanta.

Meanwhile, the Dolphins are banged up at a few positions.

Kicker Caleb Sturgis is dealing with a groin injury and will several practices.

Tight end Charles Clay (knee), QB Pat Devlin (hamstring), CB Jalil Brown (knee), and WR Stephen Williams are also expected to miss several practices.
