Seahawks DL Jason Jones (ankle) is doubtful for Sunday's game against the Lions. Jones is making the trip to Detroit after not practicing all week, but head coach Pete Carroll doesn't expect him to play. Jones signed as a free agent in the offseason and is third on the team with 2.5 sacks as a rotational lineman. His injury opens the door for seventh-round rookie Greg Scruggs, who is expected to see an uptick in playing time against Detroit.
