Porter sat out Friday with a sore knee and watched the team’s linebackers as they prepare for Sunday’s visit from Tom Brady and the New England Patriots.
He is listed as questionable for Sunday’s game.
The New Orleans Saints did a nice job of pressuring Brady during their rout the Pats on Monday night.
The Dolphins will need Porter, 32, to do the same and slow down the NFL’s AFC’s leading offense.
Porter, who has overcome an injured hamstring and sore knee, didn’t have a tackle in the team’s last meeting - a 24-12 Miami loss.
Also Friday, center Jake Grove (ankle) sat out and is doubtful for Sunday.
