Fiedler, who sat out the Tampa Bay game, will start against the Jaguars and is expected to be in the game for about 15-20 plays.
That's the plan for all the starters, with the exception of rookie tackle Wade Smith, who probably will play the entire first half.
As was the case against Tampa Bay, don't look for much action for Ricky Williams. Coach Dave Wannstedt said Williams probably wouldn't get many more carries than the two he got against the Bucs.
The Dolphins won't unveil a whole lot of their defensive wrinkles again Friday night, which is why no one should overreact to whatever happens in the game.
