At least another week for Chester Pitts

The Seattle Seahawks remain hopeful guard Chester Pitts will work his way back from microfracture knee surgery.

They aren't expecting him to play Sunday, however.

Coach Pete Carroll, addressing reporters Friday, said Pitts' knee is "still not there" and Mike Gibson will back up starting left guard Ben Hamilton.

The Seahawks' willingness to wait this long for Pitts -- he's been on their 53-man roster every week but one this season -- reflects their belief that he could significantly upgrade their line if healthy enough to play. But microfracture surgeries are serious and Pitts' situation has followed a pattern lately, with Pitts participating in practice one day, then being unable to work the next day.

Carroll also said rookie offensive tackle Russell Okung will be better prepared this week, in part because he's in better condition now that his ankle is healthier.

The chart shows the starting line combinations Seattle has used to this point in the season, with the projected lineup for Week 5 listed at the bottom.
