Taylor hurt his right shoulder during last Sunday's victory 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. Dolphins 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 practice with a hamstring injury. Center Jake Grove, who missed the past two games with an ankle injury, was limited in the workout.
The Dolphins also cut tight end David Martin from injured reserve. He had 31 catches for 450 yards and three touchdowns last season.
