Sounders FC has declined its options on four players: goalkeeper Terry Boss, defender Taylor Graham, and forwards Nate Jaqua and Pat Noonan. The names were released as part of the MLS process for the two-stage re-entry draft next month.
Any of these players still could re-sign with the Sounders, although presumably at a lower salary.
Boss however, has written on his Facebook account that he intends to retire due to the series of concussions he has suffered. That is a change from his status when the Sounders decided to shut him down to the end of the 2011 season. At that time I asked him if he was considering walking away, and he made it very clear that was not his intent.
