Dolphins OLB Joey Porter has been ruled out of Sunday's game against Tampa Bay because of a coach's decision. The Dolphins didn't give any reason for head coach Tony Sparano's decision.

The outspoken linebacker has been battling a right hamstring injury for much of the season, but he fully participated in Friday's practice.

Porter stirred things up a week ago when, in advance of Miami's game against New England, he charged that NFL officials treat Patriots QB Tom Brady differently from other quarterbacks. However, Porter failed to make a single tackle in the Dolphins' 27-17 loss at New England last Sunday.

After compiling an AFC-high 17½ sacks last season, Porter has recorded only 2½ this year.
