Dolphins bring back Ferguson

MIAMI -- Nose tackle Jason Ferguson has been re-signed by the Miami Dolphins, even though he faces a suspension for the first eight games of this season.

The Dolphins announced the signing Tuesday in a news release that made no reference to Ferguson's suspension last week for violating the NFL's policy on performance-enhancing substances.

At 35, Ferguson improves the Dolphins' roster depth, but they remain in the market for a starter at the position.

Ferguson, acquired by Miami in a trade with Dallas in 2008, has 128 career starts. He was sidelined by a season-ending quadriceps injury in November that required surgery and has contemplated retirement.
