Linebacker Joey Porter and guard Justin Smiley were sidelined with injuries Wednesday as the Miami Dolphins prepare for Sunday’s game against Tampa Bay. Porter has had a right hamstring injury for much of the season and also has a sore knee while Smiley has a shoulder injury. Porter made no tackles in Sunday’s loss at New England and has only 2 1/2 sacks this season, compared with an AFC high 17 1/2 last year.
