Veteran defensive lineman Ziggy Hood signs with Dolphins
The Dolphins, plagued by both injuries and poor run defense, made the moves Tuesday.
Taylor hurt his foot in last week's loss at Houston. He had 27 tackles and two sacks this season.
Hood, a 10-year veteran, was released two weeks ago by the Washington Redskins. He started 27 games for them at end and tackle in 2016-17.
Hood has 73 career starts and 14 sacks. Miami is his fifth team.
The Dolphins (4-4) have allowed 600 yards rushing in the past three games.
