DAVIE, Fla. (AP) -- A little more than a week into training camp, the Miami Dolphins' offensive line is riddled with question marks.
Pro Bowl left tackle Jake Long has yet to practice because he's on the physically unable to perform list. Vernon Carey has been moved to right guard after starting all of last season at right tackle. Veteran right tackle Ray Willis was signed Saturday, a few days after former Dallas starter Marc Colombo came aboard.
In the middle of the line and the middle of all the uncertainty is Mike Pouncey.
The Dolphins' first-round pick has been lining up at center with the first- team offense since July 31 -- even though 2010 starter Joe Berger is still on the roster. Pouncey missed the first two days because he was unsigned.
