Taylor, Porter sit out Dolphins practice

DAVIE, Fla. -- Linebackers Jason Taylor and Joey Porter sat out practice with injuries Wednesday as the Miami Dolphins began preparations for their game at Jacksonville on Sunday.

Taylor hurt his right shoulder during Sunday's win over the New England Patriots but returned to the game. Porter has been slowed by a right knee and hamstring injury most of the season and has frequently missed practice.

Taylor and Porter rode exercise bikes for 20 minutes at the start of drills. Coach Tony Sparano said their absence from practice was precautionary.

"We're watching them," Sparano said. "We'll see how they do."

Reserve defensive back Nathan Jones sat out with a hamstring injury. Center Jake Grove, who missed the past two games with an ankle injury, was limited in practice.
