An ankle injury caused him to miss practice for a second consecutive day. Locklear already was playing with a tender knee.
Veteran Tom Ashworth and second-year pro Ray Willis split time at right tackle in practice Thursday. Ashworth has started in a Super Bowl for New England, so he has experience, but his first season in Seattle has been a bit of a struggle. He has given up sacks whenever he has gotten onto the field, first in the exhibition season and again when Seattle needed him briefly in the season opener.
Ashworth was working at left tackle in the opener. He might be more comfortable on the right side. The team previously tried him at guard, although that experiment was short-lived.
Willis, meanwhile, has flashed potential in training camp and minicamps. He's a massive man at 6-foot-6 and close to 330 pounds. He has a mean streak that coaches like, but he has not been overly impressive in exhibition games, and his lack of experience would be a liability were he to play Sunday.
Locklear has started games after missing practices in the past. He missed practice before the team's game at Chicago earlier in the season, only to start and perform reasonably well. He has given up 1.5 sacks in six starts this season.
Coach Mike Holmgren has already threatened to shake up the lineup this week. Rookie Rob Sims is splitting practice time at left guard, where Chris Spencer has struggled to find his bearings. Spencer has plenty of talent, but he is a natural center playing out of position. Sims is a natural guard with outstanding strength.
--WR Bobby Engram (thyroid condition) dressed for practice Thursday and did some drill work off to the side. He remained questionable on the injury report. The team has good depth at the position, so there is no pressure to rush Engram onto the field. Seattle is generally conservative with injuries.
--LG Floyd Womack returned to practice Thursday and worked with the scout team, his first action since suffering a sprained knee against Arizona in the second game of the season. Womack struggled early in the season, but the team will consider putting him back in the lineup because replacement Chris Spencer hasn't improved substantially. Womack worked at right tackle with the scout team Thursday.
--RB Shaun Alexander (broken foot) is doing some treadmill work this week. He won't practice, most likely, but the team is confident Alexander will be back for the Nov. 6 game against Oakland.
--DT Marcus Tubbs missed practice again Thursday. He remains questionable on the injury report. The team expects him to play Sunday. Tubbs is resting a sore knee.
--LB D.D. Lewis missed practice again Thursday. He remains questionable on the injury report with a turf-toe injury that could linger throughout the season.
--RT Sean Locklear missed practice again Thursday. The team downgraded him to questionable on the injury report. Tom Ashworth and Ray Willis split reps at right tackle in practice.
