More Moves

The Dolphins added three players to their active roster on Wednesday, including one familiar face. Meanwhile, Zach Thomas spend the day in Pittsburgh being evaluated three days after what originally was described as a minor car accident.

Coach Cam Cameron said Thomas was being evaluated for whiplash, although an earlier Internet report suggested doctors were examining him for a possible concussion.

Cameron said he didn't want to speculate about a concussion, saying he would have a more definitive answer on Thursday.

If Thomas indeed sustained a concussion, it would be his second in a little over a month and would raise doubt about his availability for the rest of the season, if not put in jeopardy his career.

In terms of the roster additions, the three players officially signed on Wednesday were tight end Aaron Halterman, defensive end Quentin Moses and safety Lance Schulters, who played for the Dolphins in 2005 before playing for Atlanta last season.

Moses was a third-round pick of the Oakland Raiders this year but failed to make the team; Halterman was promoted from the Dolphins practice squad.
