Starting left tackle Bradley Sowell returned to practice in limited fashion on Thursday for the Seahawks, the team's first official workout of Week 9 ahead of its Monday Night Football matchup with the Buffalo Bills at Seattle's CenturyLink Field. 

Sowell, who injured his knee in the club's Week 7 game against the Arizona Cardinals, was held out of practice all last week and listed as questionable heading into this past Sunday's game against the Saints in New Orleans. He was ultimately declared inactive, as rookie George Fant started in his place. Earlier Thursday, Seattle head coach Pete Carroll called Sowell's status day to day.

"We're going to work him out each day and see how he goes and see where he is by the end of the week," Carroll said of Sowell. 

Sitting out Thursday's practice for the Seahawks were running back Thomas Rawls (fibula), tight end Luke Willson (knee), defensive end Michael Bennett (knee), strong safety Kam Chancellor (groin), cornerback DeAndre Elliott (hamstring), and linebacker Kevin Pierre-Louis (ankle). Practicing in full were quarterback Russell Wilson (knee/pectoral), defensive end Cliff Avril (groin), tight end Jimmy Graham (knee), and defensive tackle Tony McDaniel (ankle). Along with what he said about Sowell, Carroll also gave updates on Willson, Bennett, Chancellor, Pierre-Louis, Wilson and receiver Tyler Lockett at his Thursday press conference.

The big news for the Bills, meanwhile, is that starting running back LeSean McCoy was a limited participant at Thursday's workout. McCoy, Buffalo's leading rusher with 598 yards, missed practice last week with a hamstring injury and was held out of the team's Week 8 loss to the New England Patriots. In seven games this season McCoy has averaged 5.3 yards per carry and scored seven total touchdowns, six rushing and one receiving. 

"I hope good, because we need him," Bills head coach Rex Ryan said on a conference call with Seattle-area reporters Thursday when asked about McCoy's chances of playing against the Seahawks. "He did a lot more this week. He really didn't practice this past week. But he was out there practicing, so real hopeful that he goes this week."
