Griffin was the biggest unknown as the week progressed after suffering an ankle injury suffered in the first half of Seattle's Week 17 win over Arizona. After not practicing the first two days this week, Griffin was a full participant on Thursday.
With Griffin appearing to be ready to play, the focus will turn to Sweezy and if Seattle's offensive line can be entirely intact. Sweezy suffered a sprained foot in the first half of Week 16 against Kansas City. Seahawks coach Pete Carroll has described the injury as being a three to four week recovery, but said Sweezy feels confident he'll be able to play against the Cowboys.
