He was officially listed as questionable Friday on the team's injury report.
Lynch carried the ball 21 times for 85 yards in Seattle's 20-16 loss.
Lynch rushed for 1,204 yards and 12 touchdowns last season. He was exceptional the final nine weeks of the regular season when he was the most productive back in the NFL. Over those final nine weeks, Lynch rushed for 941 yards and nine scores. He puts most of the credit on the offensive line that finally clicked with the blocking schemes assistant head coach Tom Cable spent the first half of the year trying to perfect.
Coming off the finest season of his career, Lynch was rewarded in March when he agreed to a $31 million, four-year contract to stay in Seattle and bypassed an opportunity at free agency.
